INTEODUCTION. 



The additions made to the Library of the Society during the last 

 twenty years have rendered the Catalogue of 1866-77 obsolete. 

 The Council therefore resolved to issue a new edition in a 

 somewhat modified form, by which, it is hoped, its use will be 

 facilitated. Journals and the publications of Societies, which 

 formed Part II. of the previous edition, are now incorporated in 

 the general alphabetic arrangement. 



The works forming part of Linnseus's own library are distin- 

 guished by the letter %. 



September 1896.
