Abstract

VOLUMES 148 inclusive, covering the years 1939–42, of the Proceedings of the Academy, Vienna, in which are published articled astronomy, mathematics, meteorology, technology, have recently been received. The number of articles contained in each volume is substantially the same; but this is considerably less than for volume 147, for 1938. A reduction in the page size of the pamphlet was made in 1940, and, in addition, in the following year, paper of an inferior and darker quality was introduced. The majority of the articles are theoretical. Of the experimental articles, those on the light properties of stars by K. Graff, and the “Communications from the Institute of Radium Research”, of which several appear in each volume, are worthy of special mention. As is to be expected, the latter deal mainly with the properties of uranium and thorium, fission products and the effects of neutron bombardment. The purely mathematical papers include one on Laguerre's polynomials by A. Erdelyi, on the Euler-Maclaurin series and Bernoulli's numbers by A. Klingst, and on differential geometry by K. Strubecker.
