Xll PREFACE. 



for supplying many titles of papers and books wliicli I should 

 otherwise have missed. 



In spite of inevitable shortcomings, I believe that this 

 volume will prove to be of greater use than its predecessors 

 on the same topics. Dryander*s Catalogue of the Banksian 

 Library, which is arranged most minutely as to subject, and 

 the systematic portion in both editions of Pritzel's Thesaurus, 

 are less convenient for reference than the one alphabetic 

 index which closes this book.
