﻿226 ON THE CLASSIFICATION OF BIRDS. 



uniform in size, of about twenty volumes ; for many 

 of those of which the ordinary copies are in quarto, have 

 been likewise printed in folio. They are all necessary for 

 the consultation of ornithological writers, and for deter- 

 mining the names of birds ; but their collective cost is so 

 enormous, that few public libraries, or private indivi- 

 duals, would think of expending such a sum on books 

 belonging only to one department of natural history. 

 There are, nevertheless, not wanting, even in this country, 

 individuals who enrich their libraries with a selection 

 of the best works of this nature. It is, therefore, with 

 a view to guide such patrons in their choice, that we 

 shall now divide the last list into two classes ; the first 

 containing such works as are chiefly valuable for refer- 

 ence, but not, like those in the second, pre-eminently 

 beautiful in the execution of their figures. To these we 

 shall annex the current prices, where known, as marked 

 in some of the catalogues of the London booksellers.
