My grateful thanks are due to Mr. Harry M. Ferren, Pro- 

 fessor of German in the Pittsburgh North Side High School, to 

 Mr. Ferdinand Berger, Professor of German in the University of 

 Pittsburgh, to Dr. J. F. L. Raschen, Professor of German and 

 Dr. L. W. Burdick, Assistant Professor of German in the Uni- 

 versity of Pittsburgh for valuable advice and suggestions re- 

 ceived in the preparation of the work. 



It is earnestly hoped that the book may serve its purpose as 

 an aid to those, who, with a moderate knowledge of German are 

 beginners in the German literature of chemistry.
