    Notes: A method is given of deriving the main features of the seismological travel-time tables from various assumed forms of the ray velocity variation. Attention is drawn to the utility of the functions dΔ/dp/dΔ and Σ in this connection. Attention is also drawn to the utility of the approximate formula v = arb which is both simple in application and gives very accurate results in parts of the Earth's interior, notably the region between the crustal layers and the level reached by rays for which Δ= 20°.

    Description / Table of Contents: Summary To the series of yearly values of rainfall happened in Mantua from 1841 to 1941 has been applied the periodal analysis after the method of Vercelli. From this are derived compounded waves almost periodical and almost persistent of 34, 21, 16.5, 11.4, 8, 5.6, 4.2, 3, 2 years. The waves found by these means are compared with the corresponding ones of Triest and Padua.
    Abstract: Zusammenfassung An Hand der jährlichen Werte der Niederschläge, welche in Mantua von 1841 bis 1941 gefallen sind, wird die Vercelli Periodal-Analyse angewendet. Man erhält fast-periodische und fast-beständige Komponentewellen, die Perioden von 34, 21, 16.5, 11.4, 8, 5.6, 4.4, 3, 2 Jahre haben. Die gefundenen Komponenten werden mit den entsprechenden Wellen von Triest und Padua verglichen.
    Notes: Riassunto Alla serie dei valori annui delle precipitazioni atmosferiche avute a Mantova dal 1841 al 1941 si applica l'analisi periodale del Vercelli. Si ottengono onde componenti quasi-periodiche e quasi-persistenti di anni 34, 21, 16.5, 11.4, 8, 5.6, 4.4, 3, 2. Le onde trovate si confrontano con quelle corrispondenti di Trieste e Padova.

    Description / Table of Contents: Summary Applying the proceedings of Malkin verified by experiments of Ramsayer is studied the influence on the declination in upper levels of some magnetic anomalies in Italy, for which exist detailed reliefs in the vertical component (Colli Euganei, Stromboli). For the anomalous zones capable to influence the maintaining of the route in compass-airnavigation special maps are proposed containing the position of the isogons at various fondamental heights, an instance of which is presented for the isle of Stromboli. An examination of the magnetic anomalies in Italy shows the zones of probable and those of secure danger for compass-airnavigation as long as it will not be possible to prepare maps in the proposed type. For the rest of the Italian air-space the opportunity is prospected to construct the isogons for the pilots on the basis of the normal field.
    Abstract: Zusammenfassung Nach dem Malkinschen Verfahren wird der Einfluss einiger magnetischer Störgebiete (Colli Euganei, Stromboli) auf die Flugnavigation berechnet. Es wird vorgeschlagen, wo nötig, spezielle Deklinationskarten mit den Isogonen zu verschiedenen Haupthöhen vorzubereiten; ein Beispiel hiefür wird für die Insel Stromboli gegeben. Die Störgebiete, welche eine Gefahr für die Flugnavigation mit dem Magnetkompass bilden können, werden für Italien begrenzt. In dem übrigen Raum in Italien wird als das beste Verfahren für die Flugnavigation vorgeschlagen, die Isogonen nach dem vom Verf. berechneten Normalfeld darzustellen.
    Notes: Riassunto Con i procedimenti del Malkin, verificati sperimentalmente dal Ramsayer, viene intrapreso lo studio dell'influsso sulla declinazione in quota di alcune anomalie magnetiche in Italia, per cui esistono rilievi di dettaglio nella componente verticale (Colli Euganei, Stromboli). Per le zone anomale, capaci di influenzare il mantenimento della rotta nella navigazione aerea con la bussola, vengono proposte carte speciali con l'andamento delle isogone a varie quote fondamentali, di cui si presenta un saggio per l'isola di Stromboli. Attraverso un esame delle anomalie magnetiche in Italia, si indicano le zone di probabile e quelle di sicuro pericolo per la navigazione aerea con la bussola finchè non si potrà costruire per esse carte del tipo proposto. Per il rimanente spazio aereo italiano si prospetta l'opportunità che le isogone per i piloti siano costruite sulla base del campo normale.

    Description / Table of Contents: Summary The results of dry and wet katathermometer observations taken during 18 months at Messina and the Internat. Polar-Year 1932–33 at Mogadiscio are given and analysed. Together with the inference of the general bioclimatic characteristics it is explain the geoclimatic behaviour of the cooling power through its yearly variation. With regard to the equations proposed for the representation of the cooling power it is shown that a great limitation for their validity is necessary. Moreover, to assure a complete synthetical description of the climatic elements it is demonstrated that besides the dry cooling power also the wet should be take into account.
    Abstract: Zusammenfassung Die Ergebnisse der katathermometrischen Messungen in Messina und in Mogadiscio werden beschrieben und erörtert. Ausser der Ableitung der bioklimatischen Eigentümlichkteiten, wird gezeigt, wie die Abkühlungsgrösse auch ein geoklimatisches Verhalten aufweist und zwar durch ihren jährlichen Gang. Aus anderen Betrachtungen wird nachher hervorgehoben, dass die Darstellung der Abkühlungsgrösse durch Formeln in Funktion der meteorologischen Faktoren klimatologisch kaum möglich ist und nur bei grosser Vorsicht benutzt werden kann. Zulezt wird die Notwendigkeit der gleichzeitigen Verwendung der feuchten Abkühlungsgrösse zusammen mit der trockenen geprüft.
    Notes: Riassunto Vengono analizzati i risultati delle misure catatermometriche eseguite durante 18 mesi a Messina ed in diversi mesi dell'Anno Polare Internazionale 1932–33 a Mogadiscio. Insieme alla deduzione delle caratteristiche bioclimatiche generali si illustra il comportamento geoclimatico del potere refrigerante attraverso il suo andamento annuale. Seguono considerazioni che giustificano la limitazione della validità delle formole per la rappresentazione del potere refrigerante in funzione dei fattori meteorici. Si dimostra inoltre come per la definizione sintetica completa degli elementi climatici occorra far intervenire oltre il potere refrigerante secco anche quello umido.

    Description / Table of Contents: Summary After having collected by a very simple method the atmospheric dust of Venice in different places and various conditions of weather, this was then analysed. The quantity of salt found in it is put into relation with the wind and rain.
    Abstract: Zusammenfassung Der Verf. berichtet über die Salzgehalt-Bestimmungen welche er, mit einem einfachen Verfahren, für den atmosphärischen Staub in verschiedenen Orten von Venedig und Umgebungen, sowie bei verschiedenem Wetter, durchgeführt hat. Die Engebnisse sind mit der Wind- und Niederschlag-Verteilungen verglichen und erläutert.
    Notes: Riassunto Raccolta con un metodo molto semplice, venne analizzata la polvere atmosferica di Venezia in diverse località ed in condizioni diverse di tempo. La quantità di sale trovata viene posta in relazione col vento e con la pioggia.
