ASTRONOMY. 



163 



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

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

 is " untechnical," and the " terse and vigorous ^' style makes it most in- 

 teresting from beginning to end. There are numerous references to 

 the original sources of information. 



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

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



ASTRONOMICAL BIBLIOGRAPHY, 1886. 



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

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

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

 extent of including all titles that Lave come under the com[)iler's no- 

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

 publications themselves, the imprints, etc., may be imperfect. The 

 prices quoted are generally taken from Friedliinder's Naturne Novitates, 

 in German " mark " ( L mark = 100 pfennige = 1 franc 25 centimes = 25 

 cents, nearly). 



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

 without special explanation. (" Compt. Eend." is, of course, the 

 Comptes rend us hebdomadaires des seances de I'Academie des sciences, 

 Paris, and " Month. Not." the Monthly Notices of the Eoyal Astronom- 

 ical Society.) Among the imprint and other abbreviations there occur: 



Bd. = Band, 

 d. = die, der, del, etc. 

 ed. = edition,

 n. d. = no date, 

 n. p. = no place of publication. 



n. F. = neue Folge. 



n. 8. =: new series.

pi. ^ plates. 



pt. =^ part.

The alphabetical arrangement is made to serve as an index to the 

 present record, by inserting after the subject-heading, the pages of this 

 review (p* — ) on which the different subjects are noticed. 



In the references to journals the volume and page are simply sepa- 

 rated by a colon; thus: 5 :S1 indicates volume 5, page 81.
