PREFACE. 



An attempt has been made in the following pages to collect the titles 

 of the principal books on Chemistry published in Europe and America 

 from the rise of the literature to the close of the year 1892. The term 

 Chemistry is taken in its fullest significance, and the Bibliography will be 

 found to contain books in every department of chemical literature, pure 

 and applied ; the range of topics will be seen in the Subject-Index and 

 their distribution in the Table at page xiii. The Bibliography is confined,, 

 however, to independent works and their translations, and does not, as a 

 rule, include Academic Dissertations (which are so numerous as to require 

 a special catalogue), nor so-called ''reprints " or "separates" (Separat- 

 Abdriicke) ; of the latter only a few score are ordinarily printed and they 

 must be regarded as belonging to periodicals. No attempt has been made 

 to index the voluminous literature of periodicals except in the Section of 

 Biography as noted below. Full bibliographical details have been given 

 whenever possible, but the necessity of transcribing titles from catalogues 

 of many degrees and varieties of imperfection has caused inequality in 

 the fulness of the titles ; a considerable number of books have been 

 personally examined, these are indicated by adding the pagination, and 

 for these alone can the compiler be wholly responsible. 



To facilitate reference the work is divided into seven Sections : 



I. Bibliography. 



II. Dictionaries. 



III. History. 



IV. Biography. 



V. Chemistry, pure and applied. 

 VI. Alchemy. 

 VII. Periodicals. 



It is believed that these divisions are so clearly marked that few doubts 

 can arise as to the position of a given work ; moreover, cross-references
