﻿PREFACE. 



The Select Bibliography of Chemistry, 1492-1892, was published in 

 1893 ; this First Supplement includes works omitted in that volume and 

 brings the literature of chemistry down to the close of the year 1897. In 

 the following pages the lines of the original work have been followed, the 

 term chemistry being taken in its fullest significance ; the range of topics 

 will be seen in the Subject-Index and their distribution in the Table 

 on page vii. This Supplement does not embrace Academic Dissertations, 

 a catalogue of which is nearly ready for the press. 



As in the first volume, the titles are grouped in Sections with a view to 

 facilitating reference : I. Bibliography ; II. Dictionaries ; III. History ; 

 IV, Biography ; V. Chemistry, Pure and Applied ; VII. Periodicals. 

 Section VI., Alchemy, has been dropped. The scope of each Section is 

 explained in the first volume, and it need only be here pointed out that in 

 each (excepting those of Biography and Periodicals) the titles are arranged 

 alphabetically by authors, translations of each work following the origi- 

 nal in the alphabetical order of the English names of the languages. The 

 order is the same as in the Table on page vii. In the Section of Biog- 

 raphy the titles are placed under the names of the persons described, with 

 cross-references from the authors. 



In the preparation of this Supplement I have been fortunate in secur- 

 ing, through the agency of the Smithsonian Institution, the co-operation of 

 eminent men of science and letters in several parts of the world. In 

 response to requests addressed to the gentlemen named below, they con- 

 tributed more than two thousand titles, as shown in the statement : 

 Titles Contributed.* 



13 Arabic, by Dr. Y. Sarriif, of Cairo, Egypt. 



20 Finnish, by Professor Ed. Hjelt, of Helsingfors. 



* The number of titles here given does not agree in each case with those in the 

 Table on page vii, because many were duplicates, and some were Dissertations.
