    Description / Table of Contents: Zusammenfassung Es ist eine statistische Beziehung, zwischen der atmosphärischen Leitfähigkeit am Boden und dem Vertikalstrom Luft—Erde zu erwarten; an Hand der Beobachtungsergebnisse von achtzehn Stationen kann diese Beziehung mit wenigen Ausnahmen bestätigt werden. Auf Grund davon wird ein Parameter bestimmt, der an verschiedenen Stationen gleich-zeitig variieren sollte. Für vier, weit auseinander liegende Stationen zeigt dieser Parameter während einer fünfjährigen Periode tatsächlich geringere Schwankungen von Station zu Station innerhalb der einzelnen Jahre als für die einzelne Station von Jahr zu Jahr. Der Jahresgang des Vertikalstroms für die ganze Erdkugel wird geschätzt; seine Schwankungen stehen im allgemeinen in Übereinstimmung mit der Gewittertheorie für die Erhaltung der elektrischen Erdladung. Im Anhang wird eine Übersicht über die Beobachtungen der Leitfähigkeit und des Vertikalstroms in Canberra gegeben.
    Abstract: Résumé Il doit exister une relation statistique entre la conductibilité atmosphérique au voisinage du sol et le courant vertical air-terre; les observations de 18 stations vérifient cette relation, à quelques exceptions près. On détermine un paramètre dont la valeur devrait varier simultanément en des endroits différents. Or pour quatre stations fort éloignées les unes des autres, ce paramètre présente pendant cinq ans des variations plus faibles de station à station au cours de l'année que d'année en année en un même endroit. On essaye d'estimer la marche annuelle du courant vertical pour l'ensemble du globe; ses variations concordent en général avec la théorie des orages concernant la permanence de la charge terrestre. En appendice on donne un aperçu des observations de conductibilité et du courant vertical à Canberra.
    Notes: Summary A statistical relation may be expected between the conductivity of the atmosphere near the ground and the air-earth conduction current. Results from 18 stations are examined and with a few exceptions such a relation is found to hold. Following from this result a parameter is determined which, statistically, should vary simultaneously at various stations. At four widely separated stations this parameter, over a period of five years, shows less variation from station to station in the same year, than it does from year to year at the same station. The annual variation of air-earth current over the whole globe is estimated. Its fluctuations generally accord with the thunderstorm theory of the maintenance of the earth's electric charge. A summary of air earth current and conductivity observations at Canberra is appended.

    Notes: [Auszug] DUPERIER1 has analysed the first harmonic of the apparent solar diurnal variation of cosmic rays at London, using a method due to Thompson2. He finds that the first harmonic for any month has three components, namely, (i) a mean solar vector M, (ii) a vector, A, ...

    Notes: [Auszug] BURSTS of cosmic radiation were observed in an ionisation vessel 14 cm. diameter and 27 cm. high, filled with carbon dioxide at 10 atmospheres pressure, and completely surrounded by 10 cm. of lead. The sizes of the bursts were estimated as ranging between 35 and 1,800 rays, while the average ...
