PREFACE. 



The Select Bibliography of Chemistry, i 492-1 892, was 

 published in 1893 ; the First Supplement, published in 1899, brought 

 the literature down to the close of the year 1897. The present work, 

 constituting the Second Supplement, continues the subject five years 

 later, to the close of the year 1902 ; in it are preserved the same sub- 

 divisions adopted in the main work, and it includes additions to Sec- 

 tion VIII, Academic Dissertations, which was published separately in 

 1901. To summarize, the present work contains titles of books pub- 

 lished between 1898 and 1902, both inclusive, under the following 

 heads : 



I. Bibliography. 

 II. Dictionaries. 

 III. History. 

 I\'. Biography. 



V. Chemistry. Pure and Applied. 

 VI. Alchemical Literature in the 19th Century. 

 yil. Periodicals. 

 VIII. Academic Dissertations. 

 No attempt has been made to iiidex books and periodicals, as this 

 is accomplished in the International Catalogue of Scientific Literature, 

 directed by the Royal Society, London, and that undertaking is not 

 duplicated in the present work.
