INTRODUCTION 



full alphabetical index of classes and sub-classes is appende 

 forming a key, not merely to this catalogue, but to the books 

 themselves as they stand on the shelves, where the order of 

 ascending decimals coincides exactly with that followed in 

 the catalogue. Periodicals and transactions are, however, 

 shelved apart from books of a non-serial character. 



A second index is added of author's names. 



The general editing of this Subject Catalogue has bee 

 entrusted to Miss Helen Paterson, Chief Assistant in the 

 University Library. 



The different lists have had the benefit of revision by the 

 teachers of the several subjects.
