Abstract
THIS very handy little volume is now widely known, and the issue for 1923 shows no falling off in its general utility; it contains all the usual calendar information, and has tables and descriptive matter dealing with all classes of heavenly bodies; there are also physical, mensurative, and geographical tables. The only point in these tables that seems to call for some criticism is the section relating to comets. The orbits given are in many cases by no means the latest or most accurate available; the latest return of Encke's referred to is that of 1914, though it has been seen since then, in 1918 and 1921. The date given for the perihelion passage of the comet Pons-Winnecke in 1921 is June 20, which is eight days too late; it is also curious that this comet is called simply Winnecke's, forgetting that it was first found by the French astronomer Pons, and that its periodicity was known long before Winnecke found it in 1858.
