BROTHERS PUBLISHERS NEW YORK AND LONDON COPYRIGHT, 1946, BY HARPER & BROTHERS. PRINTED IN THE UNITED STATES OF AMERICA. ALL RIGHTS IN THIS BOOK ARE RESERVED. NO PART OF THE BOOK MAY BE REPRODUCED IN ANY MANNER WHATSOEVER WITHOUT WRITTEN PERMISSION EXCEPT IN THE CASE OF BRIEF QUOTATIONS EMBODIED IN CRITICAL ARTICLES AND REVIEWS. FOR INFORMATION ADDRESS HARPER & BROTHERS L-Y This book is an effort to rescue the ancient love of simple star-gazing from the avalanche of mathematics and physics under which modern astronomy threat¬ ens to bury it. AUTHORITIES USED IN THIS BOOK For the benefit of any professionals who may happen to see a copy of this Primer, it may be well to list the principal authorities used in its compilation. In the charts and pictures of the various groups all star positions (refigured for precession to 1950) are derived from the Yale Catalogue of Bright Stars by Schlesinger and Jenkins. Stellar magnitudes as given in that catalogue have also been used. Star distances mentioned in the text are figured from the Yale parallaxes. Pronunciations are given in my own phonetic spelling of the diacritical marks used in the authorized list of pronuncia¬ tions adopted by the American Astronomical Society, plus a supplementary list by George A. Davis, Jr., one of the mem¬ bers of the committee, published in Popular Astronomy. The orientation of all charts of the groups for various times has been checked for altitude and azimuth by means of the tables in H. O. 214. [vi]
