Abstract
THE receipt of the usual annual astronomical handbook from Madrid (“Anuario del Observatorio Astron6mico de Madrid”) in the unusual circumstances that exist to-day in Spain, calls for at least a brief comment. The 1937 handbook contains current tabular matter that is likely to be of general use to observers in Spain—astronomical elements, tables of sunrise and sunset and of moonrise and moonset (in each case for Madrid), planetary phenomena, solar and lunar eclipses, positions of the principal nebulae and double stars, etc. A set of monthly charts is included to illustrate the night-skies as seen by an observer at Madrid, and a concluding chapter describes the use of wireless time-signals for the dissemination of standard time and the application of the signals to longitude determinations.
