BIBLIOGRAPHICAL DETAILS. 



Books that are out of print are not given, but where a new edition 

 is in course of preparation , it is so mentioned . 



Where no edition is mentioned, the title refers to the first, as the 

 only edition. A further edition generally means that the text 

 of the book has been revised and brought up to the date given . 



An "impression" is a reprint of the original, or last edition, without 

 alteration . 



Difficulty arises in some instances as to the date given. Certain 

 publishers give the date of the reprint of a book and not that of 

 the original publication ; but all the dates given in this Catalogue 

 are those of books obtainable when the Catalogue went to Press. 



Where two dates are given, that in parenthesis is the date of the 

 last edition, the following date being the year the same edition 

 was reprinted . 



Some important books appear to be old, but in various cases 

 essentials do not alter . 



The sizes of books are designated in the usual way, and a list is 

 given below of the equivalent measurement in inches . 



With very few exceptions , all books are bound in cloth covers . 



The number of pages given to each book generally includes the 

 prefatory matter.
