    Notes: Summary Numerous investigations have shown that the frequency of lightning strokes also depends on the geological conditions of the ground. In Saxonia most damages caused by lightning did not occur in the higher parts of this country. Damage in areas of primeval rocks was twice as high as in areas of younger formations (Fig. 1 and Table A). It has been observed that some areas were especially frequently struck by lightning (lightning centres). In most cases these are situated above geologic discontinuities (Fig. 2). In Austria lightning statistics were explored. The «danger factor» («Gefährdungszahl») was deducted with the formula $$\ll danger factor \gg = \frac{{damages from lightning \times 1000}}{{area of district in 100 km^2 \times mean number of thunderstorms}}.$$ These figures are registered in a map (Fig. 3). They are small in the Central Alps but in areas of old geologic formations and in some parts of the border of the Alps they reach rather high values.

    Notes: Summary Experiments to determine the thickness of glaciers by high frequency prospecting were carried out on the Austrian glacier Hintereisferner in 1938. After the war electrohydrographical measurements on glacier rivulets were carried out in the Kaprun Valley. The resistance of the glacier water fluctuates according to the time of season. It depends on the respective composition of these waters (Fig. 2). Therefore the geologic and mineralogic properties of the glacier-water may be deducted from the electric resistance. Especially the amount of surface water may be deducted (Fig. 3). An example is shown in Fig. 4.

    Description / Table of Contents: Summary After some general considerations, there are described some particular phenomena noticed about the glacier of Mandrone (Adamello). They are due to the swift retirement of the front and to the diminution of the thickness of the glacier as following: the strangling of the icetongue, glacier rigenerated, glacier dead, lake at the glacier-mouth, round ice-crevices, valley like U. They are done some suppositions on the future alpine-climatical proceeding.
    Notes: Riassunto Premesse alcune considerazioni generali si descrivono alcuni particolari fenomeni osservati al ghiacciaio del Mandrone e dovuti al rapido arretramento della fronte e assottigliamento del ghiaccio come: strozzatura della lingua ghiacciaio di rimpasto, ghiacciaio morto, lago alla bocca, crepacci circolari, valle ad U. Si fanno alcune considerazioni sul futuro andamento climatico alpino.

    Notes: Summary The writer wants to emphasize the necessity of reorganizing rationally the system of the meteorologic observatories in the Western Alps, especially of the ones on the highest mountains which are the most important for the study of the variations of glaciers. For that reorganization it is necessary to remember the variety of the climatic regions into which the Western Alps may be divided. The writer proposes the institution of other observatories employing the new important aerial-ropeways of Breauil and of Mount Blanc, and the new big and high-situated hotels and shelters which are opened all year round. The author insists particularly, on the necessity of doing up the observatories of “Col d'Olen” and “Margherita” on Mount Rosa which have not worked any more since ten years.

    Il primo problema fondamentale della Geodesia ampliato nel campo di Somigliana (1950)

    Description / Table of Contents: Summary After having recalled the extension to a spatial potential field ofLegender's formulae solving the first fundamental problem in Geodesy, the author applies such formulae toSomigliana's field, which admits the ellipsoid as one of the equipotential surfaces of the family. Such application represents the most natural extension to a three-dimensional field of the classical ellipsoidal surface formulae, and agrees with the international adoption ofSomigliana's field in dynamic Geodesy.
    Notes: Sommario Dopo aver richiamato l'ampliamento ad un campo potenziale spaziale delle formule diLegendre che risolvono il primo problema fondamentale della Geodesia, l'A. applica tali formule al caso del campo diSomigliana, che ammette l'ellissoide come una delle superfici equipotenziali della famiglia; tale applicazione rappresenta la più naturale estensione ad un campo tridimensionale delle classiche formule ellissoidiche superficiali, e si accorda con l'adozione internazionale del campo diSomigliana per tutte le speculazioni della Geodesia dinamica.

    Description / Table of Contents: Summary Starting from the general comprehensive conception that exists for us human beings, a deduction of fundamental intuition is produced. The knowledge resulting from it may be designated as short of any hypothesis, as absolute. A continuation of the specialisation is supposed to lead to branches of knowledge existing already, e. g. mathematics or physics.
    Notes: Zusammenfassung Ausgehend von dem allgemeinsten, umfassendsten Begriff, den es für uns Menschen geben kann, wird eine Deduktion fundamentaler Erkenntnisse erbracht. Das sich dabei ergebende Wissen ist als Voraussetzungslos, als absolut zu bezeichnen. Eine Fortsetzung der Spezialisierung kann auf bestehende Disziplinen wie z. B. Mathematik oder Physik hinauslaufen.

    Description / Table of Contents: Résumé Au sujet de la connection géodésique du continent Européen au continent Américain par rapport à l'intérêt géophysique, la triangulation avec des lumières mouvantes a de bonnes chances de succès. Pour aider la réalisation il faut expliquer un sujet jusque là omis. Pour la jonction des deux parts de la figure principale au lieu des lumières d'une exactitude plus grande, la condition deLaplace a été spécialisée à trois points successives de la figure, résultant ainsi la formule pour la «correction de torsion». En outre la technique des observations a été traitée, jointe aux conclusions générales.
    Notes: Summary To connect the continents, especially the European with the American one by geodetic measurements with regard to geophysical interest, the triangulation with movable high lights seems to be of a good prospect. In this method a single matter hitherto has not yet been sufficiently treated. To bring together the two parts of the principle figure on the place of the flares with higher accuracy, theLaplace' condition for three following points of the figure is specialized here, furnishing so a formula for the «bowing correction». Furthermore the technical observation methods are explained and some conclusions are added.
