A DESCRIPTIVE CATALOGUE OF 



LITERARY, MEDICAL, AND SCIENTIFIC WORKS, 

 published by Taylor, Walton, and Maberly, may be 

 had post-free on application to the Publishers. 



The object of this Catalogue is to convey a more satisfactory notion of the 

 contents of the books than can be drawn from reading the titles. Instead 

 of laudatory extracts from Reviews, general notices are given of the Chief 

 Subjects and most prominent peculiarities of the Books. The publication is 

 designed to put the reader, as far as possible, in the same position as if he 

 had inspected for himself, at least cursorily, the works described ; and with 

 this view, care has been taken, in drawing up the notices, merely to state 

 facts, with but little comment, and no exaggeration whatever.
