    Description / Table of Contents: Summary Porto Lignano is situated between Trieste and Venice. The self-reconding tide gauge have a height ratio 1∶10 and a time scale 7,2 cm/day. The method of analysis adopted for the calculation of harmonic tidal constant is that ofDoodson applied to 3 months. The tides are generally semidiurnal, near the quadrature they becom diurnal. From the harmonic constant are deducted the nonharmonic. The determined values are compared with that of Trieste and Venice.
    Abstract: Zusammenfassung Porto Lignano liegt zwischen Triest und Venedig. Der selbstregistriende Pegel reduziert im Verhältnis 1∶10 und hat einen Ablauf von 72 mm pro Tag. Die harmonischen Konstanten wurden mit derDoodson Methode von einer dreimonatlichen Reihe berectnet. Die Tiden sind vorwiegend Halbtagsgezeiten, bei den Quadraturen werden sie Eintagstiden. Aus den harmonischen Konstanten wurden die nictharmonischen Konstanten abgeleitet. Die berechneten Werte wurden mit jenen von Triest und Venedig verglichen.
    Notes: Riassunto Porto Lignano si trova fra Trieste e Venezia. Il mareografo riduce nel rapporto 1∶10 e ha uno scorrimento di 72 mm per giorno. Le costanti armoniche sono dedotte col metodo delDoodson da una serie di tre mesi. Le maree sono di tipo prevalentemente semidiurno, in vicinanza alle quadrature diventano diurne. Dalle costanti armoniche si deducono quelle non armoniche. I valori trovati si confrontano con quelli di Trieste e Venezia.

    Description / Table of Contents: Riassunto Si esamina l'azione gravimetrica di un parallelepipedo bidimensionale in base agli elementi misurabili con la bilancia di torsione nel piano verticale. Risulta che il luogo dei punti di eguali gradienti e curvature di un parallelogrammo pure estendentesi all'infinito con il lato finito in comune col rettangolo sono esprimibili a mezzo degli analoghi elementi di quest'ultimo ed 1 loro valori estremi risultano distribuiti lungo iperboli isosceli.
    Notes: Summary The gravimetric effect of a two dimensional parallelepipedon measurable by Torsion Balance in the vertical plane is examined. It is found that the places of the equal gradients and curvatures of a rectangle stretching into the infinity are orthogonal circles. The gradients and curvatures of a parallelogramm (stretching into the infinity) which has the finite side in common with the rectangle are expressed by those of the latter, their extreme values lie along isosceles hyperbolas.

    Description / Table of Contents: Riassunto Si espongono per la prima volta le formole che reggono l'oscillazione di un pendolo bicilindrico snodabile, d'interesse notevole per le questioni inerenti alle misure gravimetriche relative ed assolute come per quelle connesse allo sviluppo di un orologio astronomico a pendolo di grande precisione. Il sistema snodabile rotolante indicato dall'A. consente ad un pendolo pesante di oscillare con moto isocrono e praticamente invariabile anche con amplitudini molto forti, senza attrito sensibile e senza oscillazioni elastiche dannose. Il periodo di oscillazione viene rappresentato in funzione della traiettoria del baricentro ed esaurientemente indagato. Affinchè il periodo si mantenga indipendente dall'amplitudine dev'essere soddisfatta una determinata relazione differenziale. Oltre all'esame dettagliato della dipendenza dell'amplitudine dal periodo sono trattate le condizioni di minimo per la forma del pendolo in base ai corrispondenti valori del quoziente differenziale della traiettoria del baricentro nella posizione di riposo. La soluzione sinora nota per un pendolo matematico isocrono, il cui baricentro si muove su di una cicloide, non soddisfa praticamente nel caso di un pendolo fisico. Successivamente si indicano i moti cinematici possibili per un pendolo bicilindrico snodabile a nastro. Applicando poi le equazioni generali ad un pendolo con sistema snodabile bicilindrico tale che: 1) a seguito della forma minimale sia insensibile a piccoli allungamenti del nastro e che 2) il suo periodo dipenda soltanto dalla quarta potenza e da quelle di ordine superiore dell'amplitudine. Infine, vengono chiaramente illustrati tutti i possibili pendoli che risultano praticamente invariabili in un campo abbastanza esteso, mantenendosi isocroni anche per forti amplitudini. Un esempio numerico dimostra il notevole vantaggio nei confronti del pendolo circolare sinora usato.
    Notes: Zusammenfassung Für Aufgaben der relativen und absoluten Schweremessung wie für die Entwicklung einer sehr genauen astronomischen Pendeluhr werden ertsmalig die neuen Ergebnisse für ein Zweizylinderrollgelenkpendel dargestellt. Das von mir angegebene allgemeine Rollgelenk erlaubt, ohne wesentliche Reibung und ohne schädliche elastische Beanspruchungen ein Schwerependel auch mit sehr grossen Amplituden praktisch isochron und weitgehend invariabel schwingen zu lassen. Die Pendelschwingungsdauer wird als Funktion der Schwerpunktbahn dargestellt und eingehend untersucht. Damit die Schwingungsdauer unabhängig von der Amplitude bleibt, muss eine Differentialbeziehung erfüllt sein. Im, einzelnen werdèn die amplitudenunabhängigkeit der Schwingungsdauer und die Bedingung für die Minimumform des Pendels durch die entsprechenden Differentialquotienten der Schwerpunktbahn in der Ruhelage dargestellt. Die bisher bekannte Lösung für ein isochrones mathematisches Pendel, dessen Schwerpunkt sich auf einer Zykloide bewegt, versagt bei einem physikalischen Pendel praktisch. Für ein Zweizylinderrollbandgelenk werden die möglichen kinematischen Gelenkbewegungen angegeben. Es werden die allgemeinen Gleichungen auf ein Pendel mit einem Zweizylinderbandrollgelenk angewandt, das 1) infolge der Minimumform gegenüber geringen Bandlängungen unempfindlich ist und 2) dessen Schwingungsdauer erst von der vierten und den höheren Potenzen der Amplitude abbängt. In übersichtlicher Darstellung lassen sich alle möglichen Pendel angeben, die praktisch weitgehend invariabel und auch bei grossen Amplituden isochron sind. Ein durchgerechnetes Beispiel zeigt den erheblichen Vorteil gegenüber dem bisherigen Kreispendel.

    Description / Table of Contents: Zusammenfassung Der Verf. hat die effektiv mögliche Sonnenscheindauer in verschiedenen Punkten des «Villaggio Sanatoriale di Sondalo» berechnet und auch direkt gemessen. Die Ergebnissen werden verglichen und erörtet. Folgt eine Prüfung der Zusammenhang mit der Verteilung der Bewölkung.
    Notes: Riassunto Si calcolano — mediante la rappresentazione gratica degli archi diurni descritti dal Sole nel suo apparente moto diurno al disopra dell'orizzonte topografico visto dall'Osservatorio Meteorologico del Villaggio Sanatoriale di Sondalo — gli azimut, le altezze, gli istanti del sorgere e tramontare astronomico e topografico del Sole, mettendo in evidenza la decurtazione che il soleggiamento viene a subire a causa dei rilievi montuosi della località. Si determina, valendosi della diretta osservazione, la distribuzione del soleggiamento effettivamente possibile in diversi punti del Villaggio. Si esaminano infine i coefficienti di soleggiamento mettendoli in rapporto con la nebulosità osservata sulla località nel periodo di tempo 1940–44.

    Description / Table of Contents: Résumé Deux définitions nouvelles des climats arides sont discutées: celle deM. Gorczynski, basée sur sonfacteur d'aridité et celle de l'auteur appliquant l'indice de sécheresse. Toutes les deux définitions sont quantitatives et, par conséquence, permettent de préciser la sorte du climat aride, si les données méteorologiques sont disponibles. D'aprèsM. Gorczynski le facteur d'aridité est proportionnel àcosec ϕ (facteur de latitude), à la variation annuelle della température, ainsi qu'au rapport de précipitation, et il éxige en principe une période de 50 ans d'observations. Si le facteur d'aridité est inférieur au 20% il dénote, d'aprèsM. Gorczynski, un climat modéré. Si sa valeur est entre 20 et 40% le climat est de steppe. D'ailleurs si le facteur d'aridité surpasse le 40% le climat en question est de désert. La colonne avant dernière du Tab. I représente quelques données numériques du facteur d'aridité. La définition de l'auteur n'est pas limitée au régime de température et de précipitation, puisqu'elle comprends aussi les autres facteurs «faisant un désert» et en première ligne l'évaporation. Sonindice de sécheresse est défini comme le rapport de l'évaporation possible et de la précipitation moyenne. L'auteur a trouvé que l'indice de sécheresse inférieur à 6 dénote un climat modéré, pendant que une valuer entre 6 et 20 correspond à un climat de steppe; enfin une valeur de l'indice surpassant 20 dénote un climat de désert. Le Tab. I contient les données numériques de l'indice de sécheresse D'arrangées suivant une série croissante. Certains cas sont discutés dans lesquels l'indice de sécheresse détermine un climat plus éxactement que le facteur d'aridité.
    Notes: Summary Two new definitions of arid climates are discussed in this paper:W. Gorczynski's, definition depending on hisaridity factor and the author's own definition which is based on hisdryness index. Both definitions are quantitative and therefore allow to determine exactly a dry climate, if meteorological data are available. Thearidity factor is admitted to be proportional tocosec ϕ (latitude factor), to the annual range of temperature and to the «precipitation ratio» and requires in principle a period of 50 years of observations for its determination. According toGorczynski a value of the aridity factor below 20% determines one of the moderate climates; a value between 20 and 40% denotes a steppe climate and above 40% a desert climate respectively. Some of the aridity data are given in the last but one column of the Tab. I. The author's definition is not restricted to temperature and precipitation regime only, but includes also other «desert making factors» and particularly the evaporation. Hisdryness index is defined as a ratio of evaporation capacity and mean precipitation. It has been found that dryness index below 6 denotes a moderate climate, while between 6 and 20 it determines a steppe climate; if however it excedes 20, it corresponds to a desert climate. The numerical values of the dryness index D, arranged as a growing series, are shown in Tab. I. Some cases, in which the dryness index better denotes a climate, than the aridity factor, are discussed.

    Description / Table of Contents: Summary To the series of yearly values of the mean heights of the sea-level for the ports of Trieste and Venice has been applied the periodal analysis after the method ofVercelli. From this are derived component waves almost-persistent and almost-periodical of 22, 11,3, 8, 5,5, 4, 3, 2 years. The mean axis shows the following variations for every ten years: an ascent of 2 cm in the port of Trieste and of 2.5 cm in the port of Venice.
    Abstract: Zusammenfassung Es wird dieVercelli Periodalanalyse an den zwei Reihen, eine 50- eine 70jährige, von jährlichen mittleren Wasserständen bezüglich der Hafen von Triest und Venedig angewendet. Man erhält Komponentwellen die Perioden von 22-11,3-8-5,5-4-3-2 Jahren haben. Die entsprechenden Wellen der zwei Lokalitäten sind in einer guten Uebereinstimmung der Phase. Die Amplituden der Komponentwellen von Venedig sind etwas grösser als diejenigen von Triest. Die mittlere Achse stellt einen Aufstieg dar, welche für ein Jahrzehnt 2 cm für Triest und 2,5 für Venedig beträgt.
    Notes: Riassunto Alle due serie di livelli medi, quella cinquantennale di Trieste e quella settantennale di Venezia, si applica l'analisi periodale secondo il metodoVercelli. Si ottengono onde componenti di anni 22, 11,3, 8, 5,5, 4, 3, 2. Le onde corrispondenti delle due località sono in buon accordo di fase. Le ampiezze delle componenti di Venezia sono leggermente maggiori di quelle di Trieste. L'asse medio del diagramma di Trieste presenta una salita di 11 cm in 52 anni, quello di Venezia di 15 cm in 70 anni.

    Description / Table of Contents: Summary The author studies macro-microseismically the earthquakes which we have ascertained on the 14th of June, the 29th of June and the 15th of December in the year 1945, giving us the position of the epicentrum, which in the first two falls in Vogherese Appennino between Staffora and Nizza valleys, for the third instead north of Tortona-Alessandria connecting. The ipocentrum depth of the earthquake on the 29th of June goes from a lowest value of 9 km had macro-seismically to a maximum value had micro-seismically of about 25 km. The 15th of December one has a depth microseismically computed about 25 km, for the other on the 14th of June the outcomes are very dubious. The skate at the ipocentrum has in all these three seisms the sinking type. Having made a comparison with the geological structure of the country such a seismical activity does not seem to come from a determinate structural relieving element; it is of course owed sinkings that we had in a middle depth and has an intensity which are in conformity with transversal tectonical directresses. The biggest damages can be put in strait relation with the presence of very little alluvial formations.
    Notes: Riassunto L'A. studia macro- e microsismicamente i terremoti del 14 giugno, 29 giugno e 15 dicembre 1945, determinandone la posizione delf'epicentio, che pei i primi due viene a cadere nell'Appennino Vogherese fra la Val Staffora e la Val di Nizza, per il terzo invece a N della congiungente Tortona-Alessandria. La profondita ipocentrale del terremoto del 29 giugno 1945 oscilla fra un valore minimo di 9 Km ottenuto macrosismicamente ed un valore massimo, ricavato per via microsismica, di 25 km; quello del 15 dicembre 1945 ha una profondità, microsismicamente calcolata sui 25 km; per quello del 14 giugno 1945 i risultati sono molto incerti. La scossa all'epicentro ha sempre nei tre sismi il carattere di sprofondamento. Posta a confronto colla struttura geologica della regione tale attività sismica non sembra derivare da un determinato elemento strutturale rilevabile; essa è probabilmente dovuta a sprofondamenti avvenuti a media profondità e presenta un'intensificazione in corrispondenza a direttrici tettoniche trasversali al locale andamento del corrugamento. I danni maggiori poi si possono mettere in stretto rapporto colla presenza di esigue formazioni alluvionali sciolte su roccia in posto.

    Description / Table of Contents: Riassunto Partendo dalla nota distribuzione del potenziale nell'intorno di una sorgente puntiforme di corrente in un semiconduttore omogeneo ed anisotropo si dimostra che, al pari del caso isotropo, la distribuzione non cambia allorquando il semiconduttore è limitato da un piano comunque orientato rispetto alle direzioni principali. Si deducono quindi le formole per la resistenza specifica apparente nei singoli casi di parallelismo della linea di base nella disposizione del quadripolo con gli assi principali del tensore di conducibilità. Risulta cosi messo integralmente in evidenza il «paradosso dell'anisotropia», il cui significato per le misure di resistività in un mezzo omogeneo ed anisotropo viene illustrato con un esempio pratico.
    Notes: Zusammenfassung Ausgehend von der bekannten Potentialverteilung um eine punktförmige Stromquelle in einem homogenen, anisotropen Halbleiter wird gezeigt, dass die Verteilung wie im isotropen Falle sich nich ändert, wenn dieser Halbleiter durch eine beliebig zu den Hauptrichtungen orientierte (Ebene begrenzt ist. Die Formeln für den scheinbaren spezifischen Widerstand bei Orientierung der Basislinie einer Vier-Punkt-Anordnung jeweils parallel zu einer der Hauptachsen des Leitlähigkeitstensors werden abgeleitet. In ihnen kommt des «Anisotropie-Paradoyon» in allgemeinster Form zum Ausdruck. Die Bedeutung das Paradoxons für Widerstandsmessungen am homogenen anisotropen Medium wird an einem praktischen Beispiel gezeigt.

    Description / Table of Contents: Summary New calculation of the geological chronology according to the Pb/U ratio proved that the Euzoic Era can be divided in two Cycles of about the same length: the Caledonian-Varisciam Cycle from the beginning of the Cambrian Period to the close of the Permian, and the Alpidic Cycle from the Triasic to the present time. In these two Cycles the most important events develop in strict parallelism. During the younger Cycle the orogenetic movements are not only repeated in the same intervals as in the older Cycle but also in the same manner: strength and in other relations. Likewise the epirogenetic movements are corresponding in their position in the respective Cycle (the great and even many of their smaller features) the great changing of climates and even the phases of the evolution of organic life. The rhythm of geological history discovered in these two Cycle will give valuable indications for les known epochs (for instance the Precambrian). The geophysical explanation and interpretation cannot yet exceed mere suppositions.
    Abstract: Riassunto Una nuova determinazione delle età geologiche in base al rapporto Pb/U permettono di riconoscere che l'epoca euzoica puo venir suddivisa in due cicli di durata approssimativamente eguale: il Caledoniano-varisco del Cambriano sino alla fine del Permico, e l'Alpidico dal Trias sino ad oggi. In ciaseuno di questi due cicli le principali vicende geologiche si souo sviluppate con netto parallelismo. Infatti. nel secondo ciclo le orogenesi si riproducono non solo con gli stessi intervalli di tempo come nel primo ciclo, ma anche col medesimo andamento, con la stessa intensità e l'eguaglianza di altre caratteristiche. Analogamente, anche le epirogenesi si corrispondono in conformità alla loro composizione nei due cicli, sia nei grandi tratti come in taluni minori; del pari le oscillazioni climatiche e gli stadi di sviluppo della vita animale. Siffatta ritmicità della storia geologica rivelata nei due cicli predetti fornisce utili indicazioni per taluni periodi poco noti (p. es. Pre-Cambriano). Attualmente non è ancora possibile uscire dal campo delle induzioni per stabilire spiegazioni ed interpretazioni geofisiche soddisfacenti.
    Notes: Zusammenfassung Neuberechnung der geologischen Zeitbestimmungen nach dem Pb/U Verhältnis liess erkennen, dass die euzoische Zeit in zwei Zyklen von ungefahr gleicher Länge geteilt werden könne; den Kaledon-Variskichen vom Kambrius bis Ende Perm, und den Alpidischen von Trias bis heute. In diesen beiden Zyklen gehen die meisten und wichtigsten geologischen Abläufe streng parallel. Es wiederholen sich im jüngeren Zyklus die Orogeneses nicht nur in gleichen Zeitintervallen wie im älteren, sondern auch gleich in Art, Stärke und anderen Beziehungen. Ebenso entsprechen einander nach ihrer Stellung im Zyklus die Epirogenesen, die grossen und auch manche kleiners Züge derselben, die grossen Klimaschwankungen, und auch die Stadien in der Entwickung der Lebewelt. Der in diesen beiden Zychlen erkannte Rhythmus des geologischen Geschehens wird für weniger bekanntes (z.B. Präkambrium) wertvolle Fingerzeige geben. Geophysikalische Erklärung und Deutung kann heute über Vermutungen aoch nicht hinauskommen.

    Notes: Summary Three remarks, which are sometimes made about Freud's distiction between Ego and Id are discussed: 1. This distinction would have no analogy in other psychological concepts. 2. The essence of the “I” would be misjudged here. 3. It would be the rest of an atomising psychology, not yet arriving at the modern views of totality. Although the common parlance concerning psychic “parts” has indeed analogies in the old atomistic-psychological conceptions, these instances, as well as the conflicting drives are and have been always considered in psychoanalysis as expressions of which the person himself is the subject. Especially the concept “Id” must be looked at as equivalent to the biological total, to the concept: Person-Stern. The concept I or Ego, as a special structure of “figure” within this whole, means no split-off part, but is equivalent to what is called elsewhere “durchstrukturiertes Unterganze”. Freud entitles a certain intern organisation with the word “Ich”. He that thinks the essence of “the” I herewith misjudged, confuses word and concept—the word I contains a lot of equivocations. That there are conflicts within the person is a basic matter of fact, which is not to be pushed aside in favour of totalitarian dogmatics, this conflict must be expressed in our terminology in some way or other. Terms, by way of comparison borrowed from material situations cannot always be avoided, and need not give any inconvenience, provided reflecting over the import of the terms is practised sufficiently.

    Notes: Summary Some methods of virus purification are discussed. A distinction has been made between the purification, which can be obtained in a rather simple way (e.g. of the viruses of tobacco mosaic, tomato bushy stunt and turnip yellow mosaic) and that, which require a more complicated manipulation (e.g. of the potato virus X). Information is given about the concentration through salting out with ammonium sulphate of the virus causing the „ratelziekte” of tobacco. Previously the normal cell constituents had been mostly removed by heating the expressed sap of diseased tobaccoplants during 10 minutes at 60°C and then centrifuging off the coagulum. The partly purified virus (a brown, amorphous product has been obtained) could be preserved at 12°C during at least 3 months without losing infective power.

    Description / Table of Contents: Summary For a number of soil-organisms, injurious to plant-growth, the process of dying-off was examined at different temperatures (see curves 1–5). The relation between the period of heating (x) and the death-temperature (y) is expressed reasonably well in a curve of the general form: (y−a)√x=b. In sterilizing the soil by steaming it is desirable to keep the ground covered, also after the treatment, for about three hours. At the following temperatures a thorough killing-off is obtained: Fusarium 70°C;Sclerotinia andVerticillium (from cucumber) 60°C;Heterodera 55°C;Verticillium (from tomato) andAgriotes (wireworms) 50°C. Tomatoseed may be rendered sterile against Verticillium by submerging it it water of 45–50°C for half an hour. By this treatment the germinative power is not harmed in the least.
    Notes: Samenvatting Van een aantal voor de plantengroei schadelijke bodemorganismen werd het verloop van de afsterving bij verschillende temperaturen nagegaan (zie grafieken 1–5). Het verband tussen de duur van verhitting (x) en de afstervingstemperatuur (y) wordt goed weergegeven door een curve van de algemene gedaante (y−a)√x=b. Bij een grondontsmetting door stomen is het gewenst de grond ook na de behandeling ongeveer 3 uur afgedekt te houden. Bij de volgende temperaturen wordt een afdoende doding verkregen: Fusarium 70°C;Sclerotinia enVerticillium (komkommerstam) 60°C;Heterodera marioni 55° C;Verticillium (tomatenstam) enAgriotes (ritnaalden) 50°C. Tomatenzaad kan ontsmet worden tegenVerticillium door het een half uur onder te dompelen in water van 45–50°C. De kiemkracht van het zaad wordt hierdoor niet in het minst geschaad.

    Notes: Summary Several fungus extracts containing antibiotics were tested for fungistatic activity onCercospora nicotianae, causing the “frog-eye”-disease of tobacco in the tropics. The activity of extracts with actinomycin, streptomycin and viridin appeared very weak; an extract containing streptothricin was a little more promising; the pure clavacin is fungistatic againstCercospora at the concentration of 1 to 50.000, but burns tobacco-leaves already at 1 to 25.000. Best results gave gliotoxine extracts fromTrichoderma viride, strain 211 ofBrian. This antibiotic does not burn tobacco leaves and has a highly fungistatic and fungicidal action.

    Notes: Summary Heubner states that the oxidation of hæmoglobin to methæmoglobin by quinones should be due to a tension between two oxidation-reduction systems, the quinone-hydroquinone system and the hæmoglobin-methæmoglobin system. The authors tried to prove this statement by using various quinones with different oxidation-reduction potentials. An analysis of the results obtained suggests, however, that the oxidation-reduction potential is not the only factor determining the equilibrium. It seems that some other constitutionally conditioned factors also play an important role in this process. Experiments with non-hæmolyzed erythrocytes show that all quinones tested are able to pass through the cellular membrane of the erythrocytes without undergoing any chemical reaction. Thus, the experiments with hæmolyzed solutions and those with intact erythrocytes gave identical results.

    Notes: Summary Blastula of trout (Salmo irideus) and pike (Esox lucius), deprived of their yolk, are cultivated in the Holtfreter solution. The differenciation of the germ of the trout stops; that of the pike germ is carried on almost normally. That difference might be due to the influence of nucleic acids contained in it.

    Notes: Summary The complexes of organs induced by centrifugation of Amphibia blastulas or gastrulas interfere with the primary axis of the embryo: (a) explantates of centrifugated ectoblast are always poorer in differentiation than the same ectoblast leftin situ; (b) the complexes arising in the ventral part of the embryo have the tendency to elongate parallel to the main axis of the embryo and become connected with the head of the primary embryo; (c) grafts made on Axolotl eggs show that, when the reaction is poor, it cannot express itself except in cases of close contact with the normal organizer; (d) reciprocally, implants of strongly reacting centrifugated ectoblast placed on the ventral part of a normal gastrula of Pleurodeles induce modifications of the primary organs, viz. the transformation of the first somites into chorda. These facts lead to the conclusion that quantitative factors—and not qualitative—are effective in the differentiation of the embryo.

    Notes: Summary One of the authors has previously reported on a method which consists in the utilization of an artifical radioactive isotope (Zn63), suspended in a suitably prepared solution ofpectin, for the production oflocalized biological radiation effects. This « macromolecular occlusion » of the radioactive isotope enables one to perform intraperitoneal injections (in cases of cancer of the ovaries with severe metastatic peritoneal extension), evidently also instillations in cavernous organs, and furthermore direct intratumoral injections, without diffusion of the radioactivity outside the treated areas, as shown both by autoradiographs and controls of blood and urine specimens with a Geiger counter. The authors investigated further whether this procedure would also be suitable for obtaining, by means ofintravenous injections, alocalized radiation effect within thelungs, as presumably the radiozinc, held in the large molecules of pectin, could thus be retained in the pulmonary capillaries. Intravenous injections of such a pectin solution containing radiozinc were performed on rabbits, and autoradiographic controls gave evidence of this expected fixation within the lungs. For the purpose of preliminary clinical investigation 40 millicuries of Zn63 suspended in 6 cm3 of a 3 p. c. isotonic pectin solution were injectedintravenously in a female patient with mainly pulmonary metastases of a previously operated hypernephroma. This patient had been also submitted to X-ray therapy. In spite of a poor general condition, the injection was well tolerated. Autoradiographic controls showed quite clearly that the radioactivity remains precisely localized within the pulmonary areas. No radioactivity whatsoever was demonstrated with the counter in the urine eliminated by this patient after the injection, a fact which points to a rather amazing accuracy of the fixation of the radiozinc in the lungs. This first clinical experience seems quite interesting in view of improving the therapeutic possibilities of pathological, especially neoplastic pulmonary conditions.

    Notes: Summary One of the products of the chromic acid oxidation of the animal triterpene ambreine (V) has been identified with the lactone C16H26O2 (III) whichRuzicka and coll. had isolated by oxidation of the plant diterpene sclareol (II). This identification confirms recent findings of the authors and ofRuzicka, Dürst andJeger and shows that the hydroxyle of ambreine (V) is at the same place as the hydroxyle of sclareol which is attached to the perhydronaphtalene ring.

    Notes: Summary As Tyrothricin —Dubos's discovery of the antibiotic agent extracted from cultures ofB. brevis — does not give true aqueous solutions and retains, in the colloïdal state of the usually employed solutions, toxic properties for polymorphonuclear blood cells, we have attempted to effect the solubilization and detoxification of this compound. Treatment with formalin in given proportions results in making it water-soluble. The action of the formalin-treated compound on blood cells suspended in Ringer's solution seems to show a loss of toxicity. Subcutaneous and intramuscular injections in mice do not give visible general toxic effects, and the experiments incite to further investigations in this direction.

    Notes: Summary Rabbit muscular globulins soluble between the ionic strengths 0.15 and 0.35 are, in an almost native state, theα andβ myosins ofDubuisson. The extractability of both,α andβ, by salt solutions is greatly reduced when the rabbit muscle has been stimulated to exhaustion or poisoned with the sodium salt of monobromacetic acid till a state of rigor is obtained. This reduction however does not proceed in an absolutely similar way forα andβ, indicating probable functional differences between these two myosins. The other soluble muscular proteins are practically not affected, as far as the method permits this to be assertained.

    Notes: Summary The double refraction of oxide films on Al conditioned by an electrolytic treatment of the metal in oxalic acid, sulphuric acid and so on (“Eloxal”-layers) is due only to the disperse structure of the film (“Formdoppel-brechung”), since the substances the film consists of are optically isotropic. The optical properties depend, excepting the formation conditions, in a very characteristic manner on the crystallographic orientation of the metallic surface.

    Notes: Summary Pure liquid vinyl chloride cannot be made to polymerize through heating it up to 110°. In the presence of benzoylperoxide on the contrary polymeres with large molecules are formed by rapid reactions already at low temperatures (20°–50°). In this respect vinyl chloride distinguishes itself from the aromatically substituted ethylenes, which polymerize not only in the presence of peroxide but also in consequence of a purely thermal stimulus.

    Notes: Summary Polygalacturonic acids (pectic acids) can easily be esterified by epoxides (ethylene oxide, 2,3-epoxy-1-propanol, epichlorhydrin, etc.) in the presence of water. Under favorable conditions the degradation of the macromolecules is negligible. Some properties of the glycol esters of polygalacturonic acid which are similar to those of the methyl esters of polygalacturonic acid (pectinic acids) are described. The glycol and glycerol esters, however, are not saponified by the enzyme pectase. These compounds react much more rapidly with formaldehyde than pectinic acid which does not possess primary hydroxyl groups.

    Notes: Summary δ20;23-24, 24-Diphenyl-choladienes are easily brominated in 21-position by N-bromo-succinimide. The bromo-dienes obtained can be transformed into 21-hydroxy-, 21-acyloxy- or 21-alkoxy-dienes and the latter two split by oxidation into 21-acyloxy- or 21-alkoxypregnane-20-ones. This sequence of reactions, of which the last two may be exchanged, affords a new and simple degradation method, leading from bile acids directly to ketols of the type of the suprarenal cortical hormones.

    Notes: Summary An attempt has been made to systematize the phenomena which are included by the term of “Becquerel's effect”.Becquerel's photogalvanic effect has been thoroughly investigated on systems composed of organic redox-dyes and organic acceptors, especially regarding the speed of changes in potential and the influence of reducing and oxidizing agents. Possibilities of increasing and stabilizing the electromotor forces of the investigated photogalvanic cells have been ascertained. It has been proved that the well known rules governing inhibition of chemical reaction apply to the investigated systems.

Das Ferment wirkt nicht nur auf Acetylcholin, sondern auch auf verschiedene andere Ester mit kleinerem Molekulargewicht, die die Acetylgruppe enthalten. Es ist demnach nicht als Cholinesterase, sondern als Acetylase zu bezeichnen. Myristicylcholin beeinflußt die Cholinesterase im Blutserum des Hundes nicht, hemmt dagegen die Acetylase im Kobragift.

    Notes: Summary The Ghent strain ofTreponema pallidum loses entirely its virulence for the rabbit when mixed invitro during 1 hour at 18° C or 3 hours at 37° C with a solution of “penicillin sodium Chas. Pfizer & Co., Inc.” or with “penicillin C.S.C. sodium salt of the Commercial Solvent Corporation” at the rate of 10,000 Oxford units per cm3. The injection of 20,000 units in each testicle of the animal, when made immediately before or at the same time as the inoculation of the virus, does not protect against the infection. It is therefore possible to prevent syphilis by penicillizing the blood for transfusion. But too great amounts of the drug are required in practice. It must also be proved that chemically pure penicillin has the same treponemicid action.

    Notes: Summary β-Glycerophosphatase prepared from the intestinal mucosa of the calf was purified by fractionated precipitation with alcohol. A further concentration of the enzyme activity was attained by electrophoresis. The activity of the purified enzyme solution was reduced to ⅕ of its original value when dialysed for 48 hours atp H 4.5. Atp H 6 and atp H 10.5 only a less pronounced decrease of the activity occurred. By addition of heat-inactivatedβ-glycerophosphatase to the enzyme solution which was partly inactivated by dialysis atp H 4.5 the activity of the latter was increased by about 100%.

    Notes: Summary 2,4-Dichlorophenoxy acetic acid in lanoline applied on the base of the leaf petiols ofPrunus persica in October causes the deformation of the flowers in April. The ovaries are inexistent and the styles short. The stamens are reduced and curved downwards. The petals are lanceolate, denticulated and of a dark pink colour. The growth substance applied on the bark is transported merely upwards to the top of the branch and little to the base. The starch present in the medullar parts of the xylem disappears completely in the sections bearing deformed flowers. It is suggested that 2,4-dichlorophenoxy acetic acid disturbs the metabolism before having an effect on morphogenesis.

    Notes: Summary Report on experiments in which parakeets (Melopsittacus undulatus) were inoculated with extracts from the stool of patients with hepatitis. Transitory disease symptoms could be found in some animals. Microscopically a certain degree of degeneration and necrosis of the liver cells could be demonstrated. In another series the attempt was made to produce a hepatic dystrophia in parakeets by means of special feeding (sweet-pea seeds). The results varied; in some cases a slight necrosis of the liver occurred.

    Notes: Zusammenfassung In früheren Arbeiten wurde über die herabgesetzte Wärmetoleranz schilddrüsenloser Tiere berichtet. Werden solche operierten Tiere in einen Thermostaten von 34–35° C gebracht, so steigt ihre Körpertemperatur schneller und höher als die der normalen Kontrolltiere. Diese, nach der Entfernung der Schilddrüse auftretende, gestörte Wärmetoleranz konnte nicht mit Thyroxin gebessert werden. Sie wurde deshalb als eine Ausfallerscheinung des thyroxinantagonistischen Schilddrüsenhormons, des Thermothyrins A („Kühlhormon“Mansfelds) aufgefaßt. Dieses wird — wie bekannt — von der Thyreoidea ausgeschüttet, wenn der Organismus in die Gefahr einer Überhitzung gerät. Es vermag den Gesamtstoffwechsel (die Wärmebildung) im Interesse der Wärmeregulation herabzusetzen. In den beschriebenen Versuchen konnte der Beweis erbracht werden, daß die herabgesetzte Wärmetoleranz schilddrüsenloser Tiere mit der Verabreichung von Thermothyrin gebessert, bzw. wiederhergestellt wird. Manchmal kann sie sogar über die der normalen Kontrolltiere gesteigert werden.

    Notes: Summary Scabies and demodicosis of dogs as well as phthiriasis of pigs, dogs, and cattle may be cured by peroral application of contact poisons (di-trichlorphenyl-dichlorpropanon and bis-parachlorphenyl-trichlorbutan). Dose 0,1–0,2 g/kg body-weight during 2–4 days. In case of demodicosis the cure must be repeated 1–2 times in short intervalls. On peroral application the drugs may be detected within a few hours in the milk, fæces, and urine. The milk of the cow contains the drug during 7 to 8 days after peroral medication.

    Notes: Summary Electrical “narcosis” is produced both by repeated shocks (sinoidal alternating current, make—and—break shocks, rectangular shocks of a continuous current) and by constant galvanic current, when the current is allowed to flow through the central nervous system of mammals or men; in the case of the constant galvanic current the effect depends also on thedirection of the current in the body. The analysis of the current-effects shows that repeated shocksnever produce a paralysing effect similar to chemical narcosis and that the paralysis is caused only by the preceding maximal irritation of the central nervous system (demonstrated by the general muscular spasms). On the contrary areal narcosis is brought out by a constant galvanic current, whichdescends through the spinal cord of a mammal or a man; this effect is obtained without muscular spasms and is equivalent to the effect of chemical narcotics. Anascending galvanic current increases the central excitability and produces general muscular spasms, which are facilitated by analeptics and depressed by narcotics. This contrary variation of the central nervous systems's function, depending on the direction of the galvanic current, is only possible if there is a special micro-structure in the spinal cord of mammalians and men. We have not succeeded as yet in producing a physically easily variable narcosis by electrical methods, but many things of practical importance have been accomplished: the electrical stunning of cattle in the slaughter-houses, the electrical convulsant therapy of psychoses in humans, a new method for testing the effects, in respect to duration and depth, of drugs that stimulate or depress the nervous centers, a proof for the existence of special micro-structure in the central nervous system.
