mined by geodetic methods have been excluded 

 (and also measures of arcs of the meridian, 

 length of seconds-pendulum, etc.), while onlj'^ 

 those determinations which are astronomical 

 in their essence are given. 



In some cases this produces strange lacks, 

 yet it is probable that no better plan could 

 have been chosen. Even in bibliography it is 

 necessary to stop somewhere. 



The introduction, of eightj^-nine pages, is the 

 most generally interesting portion of the work, 

 as the statistics of astronomical bibliography 

 (only of memoirs, etc., not books, be it re- 

 membered) are here discussed. 



Some thirty thousand original articles are 

 referred to in this volume. Leaving out the 

 unimportant ones, the rest are divided as to 

 language as follows : — 



Annuals, reviews, and journals, which have 

 furnished more than a hundred articles, follow 

 in the order of importance : — ■

English 



German

Latin clearly is of secondary importance 

 only, so far as works published in journals, 

 etc., are concei'ned. French and English are 

 of capital importance ; German follows hard 

 upon ; Spanish and Polish are of the least sci- 

 entific value, especiall}- if one takes into account 

 the populations using the various tongues. 



The most valuable collections for an astro- 

 nomical librarj^ are, in general, those contain- 

 ing the most references. The number of ref- 

 erences to each set is given beside it.
