Abstract
A STAR atlas, which has now run into the fourth edition, has been prepared by Dr. H. E. Hurst, M. R. Madwar and A. H. Samaha, and published by R. Schindler, Cairo. It contains six maps which enable readers to identify the stars visible in Egypt, North Africa, southern United States, China, northern India and the Middle East. Each map represents the sky at the same time of the night with intervals of two months, or, what amounts to the same thing, the sky on the same day with intervals of four hours. Full explanations are given for using these charts which, though constructed for latitude 30° N., can be used also with sufficient accuracy for latitudes varying between 20° N. and 40° N. The local mean time of Cairo is used throughout, but the necessary correction for any other longitude can be easily made.
