    Notes: Streszczenie Prototetyka St. Leśn'ewskiego jest uogólnieniem dwuwartościowego rachunku zdań. Występują w niej obok terminów tego rachunku funktory (zarówno staŀe jak i zmienne) tych wszystkich kategorii semantycznych, jakie mogą być zdefiniowane, gdy punktem wyjścia jest kategor a zdań. W pracy zreferowane są trzy systemy prototetyki. Terminem pierwotnym dwu z nich jest implikacja, terminem pierwotnym systemu trzeciego jest równoważność. Systemy o terminie pierwotnym implikacji różnią s.ę reguŀami wnioskowania. W jednym z nich obowiązuje reguŀa weryfikacji, w drugim reguŀa ekstensjonalności. Pierwsza z tych reguŀ jest uogólnieniem następującej reguŀy rachunku zdań, wzbogaconego o terminy 0 i 1: Wyrażenie ϕ jest tezą systemu, gdy tezami systemu są oba wyrażenia powstaŀe z ϕ przez podstawienie za pewną jego zmienną symboli 0 i 1. W myśl reguŀy ekstensjonalności tezami systemu są prawa ekstensjonalności, sformuŀowane dla funktorów dowolnych kategorii semantycznych wŀaśc-wych prototetyce. W pracy podaję dowody równoważności trzech systemów prototetyki i dowód ich zupeŀności. Znaczna część wyników Leśniewskiego, zreferowanych w pracy, nie byŀa dotąd opublikowana. Opracowując te wyniki opieraŀem się na notatkach z wykŀadów Leśniewskiego, spisanych przez jego uczniów. Oryginalne notatki Leśniewskiego ulegŀy zniszczeniu w czasie powstania warszawskiego.

    Notes: Резюме Прототетика Ст. Лесневского является обобщением двузначного исчисления предложений. Выступают в ней рядом с терминами этого исчисления функторы (как постоянные так и переменные) всех тех семантических категорий какие могут быть определены, когда точкой исхода является категсрия предложений. В этом труде представлены три системы прототетики. Основным термином двух из них является импликация, ссновным термином третьей системы эквивалентность. Системы с основным термином импликации разнятся гравилами вывода. В одной из них действует так наз. правило проверки, в другой прабило зкстенсиональности. Первое из этих правил является обобщением следующего правила вывода исчисления предложений, обогащенного тєрминами 0 и 1: Вь'ражение ϕ является тезисом системы, когда тезисами системы являются оба выражения возникнувшие из ϕ через подстановку некоторой его переменной символов 0 и 1. На основании правила экстенсиональности тезисами системы являются правила экстенсиональности сформулированные для функторов любых семантических категсрий свойственных грототетике. В этом труде даются доказательства эквивалентности трех систем протстетики и доказательство их полноты. Значительная часть результатов из опытов Лесневского, представленных в этом труде, не была до сих пор опубликована. Обрабатывая эти результаты я пользовался записками составленными по лекциях Лесневского, его учениками. Оригинальные записки Лесневского подвєрглись уничтожению во еремя варшавского восстания.

    Notes: Summary When testing logical formulae for validity by applying Venn's diagrams we are using a kind of picture writing i. e. a writing in which certain facts are represented by drawings rather than sentences. This diagrammatic decision procedure may however be translated into ordinary language. Translating for instance the respective procedure of testing the mood Darii we obtain the following reasoning.

    Notes: Резюме Анонимный схолион под заглавием „О всех формах силлогизма” был переписан из парижского кодекса 2064 в 1884 году Е. Рихтером. Издал его в предисловии к коментарию Аммониуса к Первой АналитикеП ристотеля в 1899 году М. Валлис. В этом, использованном мной. схолионе рядом сложной фигурой Галеноса находятся и иные характєрные формы вывода. Среди этих форм я нашёл пять так наз. Недоказуемых стоических силлогизмов, три варианта закона транспозиции, из котсрых третьего нет в PRINCIPIA MATHEMATICA, а также некоторый вариант формы вывода, известной под названием права Евклида. Этой формой вывода пользовался Евклид в математике а Saccherius в силлогистике. Упоминает о ней впєрвые Кардан в сочинении с 1570 года, а затем Клавиус в 1574 году в коментарии к элементам Эвклида и в 1586 году в коментарии к Sphaerica Теодозиуса. Логический закон Евклида в формулировке Кардана и Клавиуса пробовал опровергнуть впервые Эргард Вейгель в 1658 году, а Яков Бернулли в 1686 году пробовал его обосновать.

    Notes: Summary The anonimous scholiumOn all forms of syllogism was copied in 1884 from the Paris Codex 2064 by E. Richter. In 1899 M. Wallies published it in the preface to Ammonius' commentary on the Prior Analytics of Aristotle. There appear in that scholium, apart from the complex figure of Galenos, other characteristic forms of inference. Among these forms I found five so-called non-demonstrable stoic syllogisms, three modifications of the law of transposition of which the third is not mentioned by the authors of Princ pia Mathematica, and a modification of the form of inference known as Euclid's law. This form of inference was applied by Euclid in mathematics and by Saccherius in syllogistics; it is mentioned for the first time by Cardan in a treatise of 1570 and later by Clavius in his commentary of 1574 on the Elements of Euclid and in the commentary on Theodosius'Sphaerica of the year 1586. In 1658 Erhard Weigel made the first attempt at refuting the logical law of Euclid as formulated by Cardan and Clavius and in 1686 James Bernoulli tried to prove it.

    Notes: Summary The aim of this paper is to give a geometric interpretation of quantifiers in the intutionistic predicate calculus. We obtain it treating formulae withn free variables as functions withn arguments which run over an abstract set whereas the values of functions are open subsets of a suitable topological space.

    Notes: Summary The theory of the square of opposition has been worked out many centuries ago as a part of Aristotelian logic of terms. In spite of its inexactness (for instance it is not possible to decide whether the termsquare of opposition is a logical or a metalogical term) this theory is included without any changes in the usual elementary course of logic. The author defines the square of opposition in the language of the logic of propositions (see Def. 1.000) and derives from this definition the usual laws of the square of opposition and several new theorems.

    Notes: Riassunto Applicando il metodo comparativo gli autori hanno studiato l'influenza del nucleo sul tenore in dipeptidasi (substratod–l alanilglicina) degli eritrociti di Vertebrati eterotermi ed omeotermi dai Pesci all'uomo. La mancanza di materiale non ha permesso di comprendere per il momento, nelle osservazioni gli eritrociti dei Ciclostomi. Con il micrometodo diLinderström-Lang eHolter si è potuto localizzare l'enzima prevalentemente nel citoplasma degli eritrociti, inoltre si è potuto accertare: I. La quantità di dipeptidasi di un eritrocita è proporizionale al volume dell'eritrocita stesso. II. La quantità di dipeptidasi per unità di volume protoplasmatico è una costante negli eterotermi. III. Negli omeotermi la quantità di enzima, per unità di volume protoplasmatico, è minore che negli eterotermi. Il tenore enzimatico degli eritrociti dei Mammiferi è inferiore (a parità di volume protoplasmatico) a quello di tutti gli altri Vertebrati studiati. Dall'insieme delle ricerche è risultata l'influenza del nucleo e della termoregolazione (dedotta dalle condizione eteroterme e omeoterme degli organismi studiati) sul tenore in dipeptidasi degli eritrociti nucleati e anucleati dei Vertebrati.

    Notes: Summary 3318 CT [bis(piperidinométhylcoumaranyl-5) cetone diméthiodide] a compound recently synthesized byA. Funke andK. von Däniken, is shown to be a potent and selective inhibitor, bothin vitro andin vivo, of the blood acetyl-cholinesterase (AcChE) of the dog. It produces acetylcholinomimetic symptoms in the animal and sensitizes different responses to acetylcholine and to stimulation of cholinergic nerves without inhibiting the blood non-specific cholinesterase (XChE). However, the action of 3318 CT appears to be limited, both in nature and in intensity, when compared to that of prostigmine, although the latter substance is a less potent inhibitor of AcChEin vitro than is 3318 CT. This difference is probably related to many factors, one of which may be the fact that prostigmine inhibits not only AcChE but also XChE; and it is not yet ascertained that XChE plays no role at all in the limitation of the effect of the stimulations of cholinergic nerves.

    Notes: Summary When decalcified nacre is treated with ultrasonic waves, the organic matrix resolves itself into very thin lacelike protidic leaflets, which can be studied with the electron microscope. Controls have been made showing that the lacelike structure is not an artifact due to decalcification, fixation, treatment with ultrasonic waves, dessiccation or electronic bombardment. The ultramicroscopic structure of the lacelike mesh-work differs with the species. At this level, morphological features appear to characterize the three classes of Molluscs studied (Lamellibranchia, Gastropoda, Cephalopoda), and perhaps different genera within the same class. The extraction, by a borate buffer, of a water-soluble constituent of the protidic material does not appreciably modify the appearance of the structures studied. The extraction, by a sodium hydroxyde solution, of a second component, leaves a fibrous residue rich in alanine and glycine.

    Notes: Zusammenfassung Aus den Arbeiten der letzten zwei Jahre auf dem Gebiet der Nebennierenrinden-Hormone stechen — was die Herstellung neuer, hochwirksamer Verbindungen anbetrifft — die Isolierung und Konstitutionsaufklärung des natürlichen Hormons Aldosteron und die synthetische Gewinnung der 9α-halogenierten Hydrocortisone hervor. Diese Ergebnisse haben den Weg zu weiteren wesentlichen Entwicklungen eines Gebietes geöffnet, das mit Cortison und Hydrocortison abgeschlossen schien. Auf dem Gebiete der Teilsynthese wurde die Herstellung von 11-oxygenierten aus 12-oxygenierten Derivaten und insbesondere aus Verbindungen ohne Sauerstoff im Ring C stark ausgebaut. Bei der letzteren liegen die wichtigsten Befunde wohl in den mikrobiologischen Hydroxylierungen in 11-Stellung und den anschliessenden chemischen Umwandlungen. Erst kürzlich ist es möglich geworden, auch die typischen Seitenketten durch mikrobiologische Methoden zu gewinnen. Die Totalsynthese der Hormone aus einfachsten chemischen Bausteinen wurde entwickelt und macht rasche Forschritte. Die Auffassungen über die Biosynthese haben konkretere Formen angenommen. Die unzähligen Arbeiten über Katabolismus und klinische Verwendung der Nebennierenrinden-Hormone konnten im Rahmen dieser Übersicht nicht einmal gestreift werden.

    Notes: Summary A previous experiment withEranthis showed thatRoentgen irradiation of “undivided” embryos led to a change in the number of cotyledons. In the present publication, the induction of anomalies of the cotyledon was shown after irradiation of early embryo stages on the mother plant in Arabidopsis thaliana, an example of a plant with “complete” embryos. Which aberration type (synkotyl, anisokotyl, trikotyl, tetrakotyl or multiple seedlings) will arise, seems to be determined neither by theRoentgen dose nor by the stage of development on irradiation. The appearance of predominately regular trikotyl types after application of 2000r, and their gradual disappearance with increasing doses in favour of the irregular trikotyl types, suggests that in the lower doses the main influences are upon the purely chemical reactions in the embryos, which are overlaid by cell damages occurring in a directly biophysical way with increase of the physical primary acts and lead to irregular growth.

    Notes: Zusammenfassung In Gewebskulturen von Hühnerfibroblasten sind Toluhydrochinon und Toluchinon unwirksam. Nach Zusatz von 10−3-M-Phosphat werden diese Substanzen antimitotisch wirksam. Der antimitotische Effekt von Toluhydrochinon + Phosphat ist erheblich grösser als derjenige von Toluchinon + Phosphat. Diese Beobachtungen können zur Deutung der antimitotischen Wirkung von Toluhydrochinondiphosphat herangezogen werden.

    Notes: Zusammenfassung Der genaue Angriffspunkt der Quecksilberpräparate an der Niere ist nicht geklärt. Widersprechende Befunde über den Effekt dieser Diuretica auf mikroskopische Veränderungen und histochemisch nachweisbare bernsteinsaure Dehydrogenase können in folgender Weise geklärt werden: Mercuhydrin in grossen Dosen führt schon innerhalb weniger Stunden zu einer schweren toxischen Nephrose in der Rattenniere, während Novurit anfangs oft langsamer wirkt. Nichtsdestoweniger ergeben beide Mittel nach 24 h ein ähnliches mikroskopisches Bild. Bernsteinsaure Dehydrogenase ist vermindert und verschwindet schliesslich vollkommen in den absterbenden Zellen. Daher ist schon in den ersten Stunden nach Injektion von Mercuhydrin eine sehr ausgedehnte Inaktivierung in den Zellen der geraden Anteile der Hauptstücke zu sehen. Dieser Effekt wird nur gelegentlich in den ersten Stunden nach Novurit beobachtet. Nach 24 h ist er aber regelmässig vorhanden. Mit beiden Präparaten konnte keine Verminderung der Enzymaktivität inHenlessche Schleifen beobachtet werden. Es wird auf die Notwendigkeit hingewiesen, dünne Schnitte zu studieren, weil die verschiedenen Anteile des Nephrons sonst kaum zu unterscheiden sind. Das Ergebnis dieser Versuche spricht eindeutig für eine Wirkung der Quecksilberdiuretica auf die Hauptstücke und nicht aufHenlessche Schleifen.

    Notes: Riassunto Gli autori hanno preparato ATP32 dai muscoli di coniglio trattato preventivamente con fosfato di sodio radioattivo. Iniettando per via endovenosa l'ATP32 e tiamina a ratti albini è stato possibile mettere in evidenza, impiegando la tecnica cromatografica su carta, la formazione nel fegato di questi animali di DP32T e TP32T. Questi risultati dimostrano che nell'animale vivente ha luogo una diretta trasposizione di gruppi fosforici dall'ATP alla tiamina.

    Notes: Résumé Exposé des données historiques et naturelles attestant des fluctuations de climat dans l'hémisphère nord au cours du dernier millénaire. Dans la zone tempérée, il y eut depuis les environs de l'an 1000 cinq époques climatiques: 1° 1000–1250, climat doux et sec. 2° 1250–1400, pluvieux et orageux. 3° 1400–1600 plus froid, moins orageux. 4° 1600–1850, avance des glaciers. 5° réchauffement progressif. Les causes de ces changements sont discutées à la fin de l'article.

    Notes: Summary The serum containing the L.E. factor loses its activity after having been put in contact with isolated cell nuclei. The electrophoretic examination shows a clear diminution of the gamma globulin and a slight diminution of the globulin alpha 2. That the factor responsible for the L.E. phenomenon can be absorbed by isolated cell nuclei is an argument in favor of the hypothesis that this factor is a substance having the character of an antinuclear anti-body, without one being able to exclude with certitude the possibility that this factor is an enzyme.

    Notes: Summary In order to test the possibility for microsomes to multiply like viruses, microsomes of chick liver were inoculated on chorioallantoïc membranes. The glucose-6-phosphatase activity, an enzyme located in the liver microsomes, was determined in the treated membranes. The activity decreased during the first 24 h after inoculation. It reached, after 48 h, from two to six times the value attained after 24 h. A suspension of heated granules, or of heatedTétrahymèna géléii, though producing the same lesions of the membrane, did not increase the phosphatase activity of the microsome fraction after 48 h. The present results are compatible with the idea that liver microsomes multiply by autoduplication.

    Notes: Zusammenfassung Die in den Kotyledonen der LeguminoseVigna sesquipedalis als «Reserve-PNA» reichlich gespeicherte Pentosenukleinsäure (PNA) nimmt rasch ab, sobald der Same zu keimen beginnt. In den frühen Stadien der Keimung ist die Abnahme des «Reserve -PNA» scheinbar aufgehoben durch die Zunahme des PNA in den wachsenden Geweben des Keimlings, während später, wenn das Alter der Gewebe sich erhöht, die Gesamtzunahme an PNA in den wachsenden Geweben allmählich die PNA-Abnahme in den Reserveorganen überwiegt. Kotyledonen, die von den Keimlingen abgetrennt und auf feuchtem Filtrierpapier geeignet warm gehalten wurden, zeigen praktisch keine Abnahme im Gehalt an «Reserve-PNA». Wenn Samen zuerst mit einer Phosphatlösung behandelt werden, die P32 enthält und dann zum Keimen gebracht werden, so findet man die Radioaktivität nicht nur im akkumulierten PNA der wachsenden Gewebe, sondern auch in dem im Abbau begriffenen PNA der Kotyledonen. Auf diesen Tatsachen fussend, wird die Möglichkeit einer makromolekularen Wanderung des «Reserve-PNA» von den Kotyledonen in den Keimling kurz diskutiert.

    Notes: Summary By means of their special histological method, the storage of plasma proteins in the histiocytes was studied by the authors in rats and mice. If injected subcutaneously, both homologous and heterologous serum proteins were stored to the same extent at the site of the injection by the histiocytes of the connective tissue. After smearing the skin with histamine or after subcutaneous injection of histamine, intensive storage of protein occurs locally in the histiocytes. Because of the effect of histamine increasing permeability, these cells accumulate in their body the plasma proteins abundantly escaping from the blood stream. Even under physiological conditions, plasma proteins are constantly taken up and destroyed by the reticuloendothelial cells and this function has a fundamental biological importance.

    Notes: Summary (1) The influence of Aldosterone (“Electrocortin”) was compared with that of 17-oxycorticosterone (compound F). The exchange of Na24 and K42 with the electrolytes of muscle was studied, with or without the addition of glucose and insulin. The diaphragm of the rat inRinger's solution was used. (2) Aldosterone (1 mg%) decreases the permeability of the muscle for Na24 and K42 if glucose and insulin are present, i.e. when glycogen is produced. Without glucose it increases Na24 exchange. (3) 17-oxycorticosterone in ten times greater concentration (10 mg%) has similar, but somewhat less influence on the permeability.

    Notes: Summary A new synthetic phenyl-ethyl-amine derivative, the 2-[N- (3′, 4′-methylen-dioxyphenylethyl)-methylaminomethyl]-tetrahydrofuran, No. 11 081, exhibits a strong protective effect against cardiac fibrillation and arrhythmias produced by various experimental methods: against fibrillation due to aconitine 3 × 10−8 on the isolated cat's heart, it is active in a concentration of 10−6−2 × 10−6. Against cardiac arrhythmias produced in the cat by adrenaline + CHCl3 or cyclopropane, it shows a protective effect by 5–10 mg/kg i.v. and even perorally by 50 mg/kg. In these tests, the antifibrillatory activity of the new compound seems to be roughly the same as that of α-fagarine, and higher than that of procaine.

    Notes: Summary An extract from pooled postmenopausal urine has been investigated for its gonadotrophic activity. Dose-response curves have been constructed for its total gonadotrophic activity (stimulation of estrogen secretion as reflected by the uterine weight increase in immature mice) and for its ICSH activity (stimulation of androgen secretion as reflected by the ventral prostate weight increase in hypophysectomised immature rats). In hypophysectomised immature rats, the extract produced repair of the interstitial cells of the testes and complete spermatogenesis. It contains, therefore, FSH as well as ICSH activity in comparable amounts, a fact which opens up interesting therapeutic possibilities.

    Notes: Summary A method for the estimation of muscle nucleotides is described. The separation of nucleotides has been accomplished by paper ionophoresis at high voltages, as well as by paper chromatography. Even little changes in the nucleotide content such as the changes in a single muscular contraction can be well observed by this method. A decrease of 0.25 µ M ATP/g/contraction (i.e. about ⅛ of the normal ATP content) has been observed in a contracted muscle, when compared with the ATP content of the resting muscle.

The process of co-agulation is subdivided into five phases, i.e. the prephase (vasoconstriction, agglutination), the first principal phase (formation of thromboplastin), the second principal phase (formation of thrombin), the third principal phase (formation of fibrin), as well as a post-phase (retraction, fibrinolysis). In this new scheme, recently discovered clotting factors and the various inhibitors could easily be incorporated into the classical picture of Morawitz. The scheme is explained briefly.

    Notes: Summary The alkaloid muscarin was isolated from fly agaric. The analyses of crystallized salts (chloride, tetra-chloroaurate,Reinecke's salt) led to C9H20O2N+ as the simplest formula. The presence of aldehyde and tri-methyl-ammonium groups, which had been assumed hitherto, could not be proved. The quaternary nature of the nitrogen atom was shown. Pharmacological tests on frog heart, rabbit gut and cats show the purely peripheral parasympathomimetic effect of the smallest doses.

    Notes: Summary In the liver of diabetic animals, other and more labile polysaccharids are formed than in that of normal animals. The iodine absorption, the speed of breakdown and the reaction with saturated ammonium sulfate of the polysaccharids isolated from the liver are different in the diabetic animal from those in the normal one. The stepwise precipitation with ammonium sulfate of the polysaccharide isolated from the liver yielded 3 fractions in the diabetic animal whereas there was only one in the normal animal.

    Notes: Summary A study was made of the influence of local (liver field) and total irradiation (1,000 rl) on the enzymatic activity of isolated liver mitochondria from adult rats. While the succinodehydrogenase activity remains unaltered, the oxydation of pyruvate — as well as the structural stability of the mitochondria — are found to be reduced, entailing a decrease in the oxydative phosphorylation. These variations remain the same even after total or local irradiation.

    Notes: Summary It is possible to dissociate the activity of different enzymatic systems of the bacteriumEscherichia coli by the action of high hydrostatic pressures. This activity is studied in the microbes after having been subjected to high hydrostatic pressure. Each enzymatic system is inhibited at different pressures. The enzymes of the bacteria submitted to pressures lower than the inhibiting limit show a residual enzymatic activity; sometimes this activity appears after a phase of lag.

    Notes: Summary The mutation of homologous genes can produce the same changes in phenotype in different mammals, animals as well as human beings. In this way the same hereditary disease can arise in man and animal. This fact permits the study of human hereditary diseases in model experiments in animals under conditions impossible to be realized in man. How far the parallelism between human beings and animals can be taken and where the limits of this parallelism are, which are the problems of the comparative heredo-pathology in detail, and how these problems may be attacked, is demonstrated here in numerous examples.

    Notes: Zusammenfassung Die viruzide Wirkung von Extrakten aus Ahornsamen auf Coli-Bakteriophagen ist durch Tannine bedingt. Verschiedene Gerbstoffe zeigen einen zum Teil sehr starken virushemmenden Effekt, wobei nur das extrazelluläre Virus angegriffen wird. Wahrscheinlich handelt es sich um eine Gerbwirkung auf das Protein des Virus. Die pflanzlichen Gerbstoffe tragen vermutlich dazu bei, die Pflanzensäfte virusfrei zu halten.

    Notes: Zusammenfassung Gewöhnliche Explosivmittel und Raketentriebstoffe entwickeln nach Zündung Reaktionswärmen, welche den Wertq v=3 kcal je cm3 nicht überschreiten. Dies gilt besonders für Kombinationen, die nur Kohlenstoff, Wasserstoff, Stickstoff und Sauerstoff enthalten. Da die Reaktionsprodukte solcher Triebstoffe alle gasförmig sind, geht im wesentlichen die Sublimationswärme der ursprünglich festen Stoffe verloren, und die Werte vonq verscheinen entsprechend niedriger. Im gleichen Sinne wirkt die relativ leichte Dissozierbarkeit von CO, CO2 und H2O bei den resultierenden Explosionstemperaturen. Um grössere Werte vonq vzu erzielen, müssen deshalb Elemente, wie Lithium, Bor, Magnesium, Aluminium und Silizium, in die Explosivstoffe eingebaut werden, die nach Detonation feste und flüssige Oxyde und Verbindungen liefern. Es wird an Hand einiger Beispiele gezeigt, dass auf diese Weise Energiemengen verfügbar werden, die im Bereich von 4 bis 7 kcal je cm3 liegen. Zur praktischen Ausführung können die genannten Leichtelemente entweder physikalisch einem gewöhnlichen Explosivstoff beigemischt werden, oder es können diese Elemente mit Wasserstoff, Stickstoff und eventuell Sauerstoff, Fluor usw. zur Verbindung gebracht und mit einem zusätzlichen Oxydationsmittel reagiert werden. Falls man in explosiven Hohlladungen potentiell selbstreagierende Einlagen aus komprimiertem Thermit oder ähnlichen Kompositionen benutzt, werden nach Detonation glühende Teilchen grosser Geschwindigkeit und grosser Durchdringungsfähigkeit ausgeschleudert. Diese Teilchen können auch als in einem Vakuum wie dem interplanetarischen Raum selbstleuchtende künstliche Meteore zu Experimenten verschiedener Art benutzt werden.

    Notes: Summary Some recent experimental results on retinal flicker and fusion are presented. The use of flicker electro-retinography provides an objective and quantitative method of testing rod and cone function independently. The results in human normal and diseased eyes are in full agreement with the duplicity theory of vision. The flicker fusion-intensity relation for man, cat, guinea pig, pigeon, frog, and gecko shows different values for (i) the maximum fusion frequencies within the cone and the rod system, (ii) the intensity level required to produce cone and rod flicker response. Records from single retinal ganglion cells in the cat's eye show fusion frequencies to be related to the initial spike frequency during slow flicker.

Erheblicher Schutzeffekt in tuberkulösen Mäusen wurde beobachtet, wenn die Therapie nicht sofort, sondern erst 9 Tage nach der Infektion einsetzte und die Behandlung mit 1 mg täglich während 21 Tagen durchgeführt wurde. In tuberkulösen Meerschweinchen, die mit 5 mg Vinactan täglich subkutan während 60 Tagen behandelt wurden, war die Entwicklung tuberkulöser Infektion in Milz, Lunge und Leber erheblich vermindert.

    Notes: Résumé Nous avons démontré qualitativement chez leBombyx mori, l'existence d'un ferment qui attaque la xanthoptérine-B, une substance fluorescente du type ptérinique qui se trouve dans les intéguments des larves de race jaune «lemon», et se transforme en une substance non-fluorescente. Le ferment se trouve dans les épidermes, tissus adipeux des larves et dans les œufs et cocons desBombyx de type normal. Chez les mutants de la race jaune, l'activité du ferment est faible ou nulle dans bien des tissus. Cependant on ne peut pas nécessairement dire que la présence de ce ferment conduit à l'absence de la xanthoptérine-B, parce que l'accumulation de xanthoptérine-B est supprimée par l'action d'autres gènes chez les mutants «Striped marking» (p s ) ou «od-translucent» (od). Dans ces derniers l'activité du ferment est en effet très faible.

Under these conditions, the respiration and the cardiac rhythm are definitely slowed down. (1) Rats irradiated in a state of deep hypothermy with lethal doses of 800 and 900 r of X-rays, are partially protected. 50% of these animals survived more than 30 days, whereas all control animals died after 17 days. (2) The same degree of protection is obtained if the cooling is made in the presence of oxygen or under an air pressure of 1.25 atmosphere.

    Notes: Zusammenfassung Es wurden einige Methoden zur Bestimmung des Wasserstoffperoxyds in biologischem Material untersucht, dessen Anwesenheit in metabolisch aktiven Organen (Leber und Niere) und in transplantablen Tumoren der Ratte und der Maus vonRondoni undCudkowicz kürzlich nachgewiesen worden ist. 1. Oxydation des CeIII zu CeIV-peroxyd, Freimachen des Sauerstoffes durch KMnO4 in Schwefelsäure und Messung des O2-Volumens im Warburg-Apparat. 2. Oxydation einer bekannten Menge SnCl2 und Bestimmung des Überschusses durch Jodtitration. 3. Eine biologische Methode, in der H2O2, das während der Atmung überlebender Gewebe gebildet wird, durch Katalase gespalten und der auf diese Weise entstandene Sauerstoff im Warburg-Apparat gemessen wird. Die ersten zwei Methoden haben sich jedoch als ungeeignet erwiesen, da beide Reaktionen von verschiedenen, im Homogenat befindlichen Substanzen gestört werden. Die bisher angewandte Titanmethode wurde verbessert, so dass man unter konstanten Bedingungen zuverlässige relative Werte erhalten kann. Die bisher festgestellten absoluten Werte sind nicht als endgültig zu betrachten, da mit der weiteren Entwicklung der Arbeitsmethoden Änderungen vorauszusehen sind.

    Notes: Summary On account of the electrostatical forces between the ions and electrons in the interior of a star, the mean molecular weight µ should be given a higher value than is usually assumed. It is believed that a satisfactory theoretical calculation of μ has not yet been given, and that it does not seem to be possible. The determinations of the chemical composition of the stars are regarded as shaky, because they are based on the value of μ.

    Notes: Summary (1) The milky way is moving “absolutely” (relative to the light-ether) with a velocity of at least 600 km/s in the direction of the “absolute” movement of the earth (A=78°,D=+40°). (2) The “point of symmetry” of the “absolute” velocities of the spirals is situated about 1,120,000 parsec from the milky way in the direction of the antapex of his “absolute” movement, and it has taken 1·83 milliards of years for the milky way to cross this distance. (3) Probably the next spirals are forming with the milky way as a center a group with a common parallel movement like that one of the milky way.
