PREFACE. 



The Select Bibliography of Chemistry was published in 1893 ; the 

 First Supplement issued in 1899 brought the literature of Chemistry 

 down to the close of the year 1897 ; this volume, forming Section 

 VIII. of the work, is devoted exclusively to Academic Dissertations, 

 especially those from the Universities of France, Germany, Russia, and the 

 United States. 



This bibliography is not an index to the chemical dissertations that 

 have appeared in periodicals, but a list of those that have been printed in- 

 dependently. When compiling the list of titles I was fortunate in se- 

 curing permission to make copies of the card-catalogues of two large 

 collections of dissertations on chemistry, those in the University Library, 

 Strassburg, and those in the library of the United States Geological Survey, 

 Washington City. I had also the opportunity of cataloguing several 

 thousand dissertations deposited by the Smithsonian Institution in the 

 Library of Congress ; the latter were chiefly of German origin. The list 

 of Russian titles was contributed by Prof. A. Krupsky, of St. Petersburg, 

 to whom thanks are offered. The manuscript catalogue thus obtained was 

 augmented by data from printed bibliographies. 



For the convenience of residents of the United States the dissertations 

 found in the libraries of the Geological Survey and of the Smithsonian 

 Institution are indicated by the letters " G.S." and "S.I." respectively. 



The subject-index has been made from the titles only and has no 

 reference to the contents of the dissertations themselves ; unfortunately 

 the titles selected by the authors often fail to indicate accurately the exact 

 nature of the essays, but to construct a subject-index to their contents has 

 not been attempted. 



In the preparation of this work I have become indebted to many 

 persons, notably to the following : Prof. K. A. Barack, Librarian-in- 

 chief, and Dr. S. Landauer, who granted me extraordinary privileges
