Abstract
“BUREAU DES LONGITUDES.”—The Annual for the year 1897 is still as complete as ever, and is a necessary vade mecum to the astronomer, physicist, and chemist. Our readers are so familiar with the usual contents of this compact little volume, that we limit ourselves to summing up the chief alterations and additions. The table of minor planets has been completed up to September 7, 1896, the number of these bodies now amounting to 431. Cometary notices have been brought up to the year 1895, while several new values for double-star elements have been inserted. Among the articles, which are always of great interest, are three from the pen of M. F. Tisserand. The first is a masterly summary of our knowledge of the proper movement of the solar system; the second, on the fourth meeting of the International Committee for the completion of the photographic map of the heavens; and the third, on the labours of the International Commission on fundamental stars., M. H. Poincaré writes on the kathode and Röntgen rays. M. J. Janssen discusses some epochs in the astronomical history of planets, and the work done at the Mont Blanc Observatory during the present year. Several discourses are also included, namely, that delivered by M. A. Cornu at the funeral of M. Fizeau, and those delivered by M.M. Janssen, Lœwy, and Poincaré at the funeral of the late Director of the Paris Observatory.
