BIBLIOGRAPHY OF ASTRONOMY*. 1887. 



I 



BY WILLIAM C. WINLOCK. 



The following subject-index of astronomy for 1887 was originally compiled as an 

 appendix to a general review of the progress of astronomy during that year, and 

 though not exhaustive, it may, perhaps, be found a useful reference list. Important 

 contributions to astronomy published during 1887 in scientific journals and trans- 

 actions of societies, as well as all more elaborate publications that have come to the 

 compiler's notice, have been included — a few titles being taken from reviews, or book- 

 catalogues. Observations of asteroids and comets, except those of the comets of 1887, 

 have generally been omitted. 



The prices quoted are usually from Friedlander's Naturae Novltates, in German 

 "marks" (1 Mark = 100 Pfennige = 1 franc 25 centimes = 25 cents, nearly.) 



The abbreviated titles will probably be readily understood by those familiar with 

 scientific periodicals without special explanation, beyond the following list of less 

 obvious contractions. 



In the references to journal articles the volume and page are simply separated by a 

 colon, thus : "Bull, astron., 4 : 94-98," indicates volume 4, pages 94 to 98.
