5. Commission des Analyses de Travaux et de Bibliographie

At the Paris congress in 1935, Messrs Dittrich, Brasch and Pogo had proposed that Commission 5 should undertake the publication of classical works of astronomy (such as Ptolemy’s Almagest, the works of Copernicus, etc.) which were untranslated or for other reasons difficult of access. The commission decided to form a sub-commission, consisting of Mr Stroobant and the gentlemen named above, to study this question, especially the means for its realization. Mr Stroobant had announced his desire to take this work in hand personally. Prof. Stroobant, however, having deceased in July 1936, and his health having been deficient during several months in advance, the sub-commission has not been able to continue its work. This is a question that ought to be taken up at the Stockholm meeting.</jats:p

16. Commission Pour les Observations Physiques des Planétes, des Cométes et des Satellites

The following works embodying researches coming within the scope of this Commission have been published since the last meeting of the Union:1. “Recherches sur la polarisation de la lumière des planètes et de quelques substances terrestres,” by B. Lyot, Annales de l’Observatoire de Paris, Section de Meudon, 3, Fase. i. Characteristic curves are found representing the fraction of light polarized in the case of the Moon and several of the planets for the angles Sun-Moon or planet-Earth and compared with curves obtained in the laboratory for light reflected by a number of terrestrial substances. Some of the conclusions arrived at are referred to in the notes below.2. La Planète Mars 1656-1929, by E. M. Antoniadi. This is based mainly on the author’s own telescopic observations with the 0.83 m. Meudon refractor in 1909 and the following years, and contains the author’s conclusions therefrom. The work of numerous earlier and contemporary observers is also summarized and compared with the Meudon observations.3. The Moon, by W. Goodacre. Contains a description of the lunar surface formations, numerous drawings, charts and photographs, and the author’s revised Map of the Moon in 25 sections.4. “Ricerche Polarigrafiche sui Pianeti. La Polarizzazione sul Disco di Giove,” by M. Maggini, Mem. della Soc. Astron. Italiana, 4.5. La Constitution des Comètes, by F. Baldet. Paris, Hermann et Cie. 1930.6. “ Halley’s Comet in its Apparition of 1909-1911,” by Nicholas T. Bobrovnikoff, Pub. of the Lick Observatory, 17, pt 11, 1931.7. “Absorptionsspektren und Atmosphären der grossen Planeten,” by R. Wildt, Nach, von der Gesellschaft der Wissenschaften zu Göttingen, Math.-Phys. Klasse, 1932.</jats:p
