 l^lan adopted in the review of astronomy for 188G, thus making this

 1890, an index for which Was published in the Sidereal MesHenger for

The principal books, memoirs, and journal articles published in 1891 

 and 1892 that have come Tinder the compiler's notice are here included, 

 and there are also a few titles that belong to earlier years but were 

 not found in time to insert in previous lists. References to series of 

 observations, preliminary orbits of comets and asteroids, reviews, etc., 

 are omitted, and to condense it into reasonable limits tlie bibliogiaphy 

 has not been made exhaustive even to the extent of printing all titles 

 that were originally collected. 



The subject headings are in alphabetical order, with a subarrange- 

 ment by authors. The references to periodicals are by volume and ])age
