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 4 '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.
