 Collections," Volume xxxiv.

" The Index Catalogue of Nebulae, etc.," includes papers, 

 memoirs, and books on nebulae and clusters alphabetically 

 arranged according to authors, with a brief note to each 

 entry expressing its contents. The works of the elder Her- 

 schel on these subjects are analyzed at considerable length, in 

 order to partly supply the great want of an edition of his col- 

 lected works. The index is practically complete to 1877, and 

 comprises no octavo pages. The astronomical life of Sir 

 William Herschel covered forty-two years. During this 

 period he published no less than sixty-nine different memoirs, 

 which are scattered through the annual volumes of the Phil- 

 osophical Transactions of the Royal Society of London 

 from 1780 to 1818. In the absence of an edition of Her- 

 schel's collected works, Doctors Holden and Hastings have 

 carried out the idea of making a full synopsis of every one 

 of his memoirs according to a model which he himself made 

 for one of his most important papers. 1 Accordingly his me- 

 moirs on astronomical subjects have been analyzed, page by 

 page, by Professor Holden, and those on physics have been 

 treated in the same manner by Doctor Hastings. The work 

 (of 114 octavo pages) supplies, in some measure, the crying 

 need for a complete edition of his writings. 



Doctor Tuckerman's " Index to Spectroscopic Literature " 

 is a stout volume of 424 octavo pages, comprising references 

 to 3829 papers by 799 authors. The astronomical portion
