ASTRONOMY. 163 



Nineteenth Century" has been so widely reviewed that it seems unnec- 

 essary to do more than merely to ujentiou it by title here. The book 

 is " untechuical," and the " terse and vigorous " style makes it most in- 

 teresting from beginning to eml. There are numerous references to 

 the original sources of information. 



Professor Young's " Ten Years' Progress iu Astronomy" has been re- 

 printed in the Sidereal Messenger (vol. G) and Nature (vol. 35). 



ASTEONOMICAL BIBLIOGRAPHY, 1886. 



The following bibliograpby is arranged by subjects, and contains jour, 

 nal articles and reijrints from transactions of societies, as well as more 

 formal publications. No pretense is made to completeness, even to the 

 extent of including all titles that have come under the compiler's no- 

 tice, and, in some cases, where it has not been possible to examine the 

 publications themselves, the imprints, etc., may be imijcrfect. Tlie 

 prices quoted are generally taken from Priedliinder's Naturju Kovitates, 

 iu German " mark " ( L mark = J 00 pfennige = 1 franc 25 centimes = 25 

 cents, nearly). 



It is hoped that the abbreviated titles of journals will be intelligible 

 witliont special exi)lanation. (" Com])t. liend." is, of course, tlje 

 Comptes rend us hebdomadaires des seances de 1' Academic des sciences,
