Preface. 



In the following pages an attempt has been made to pro- 

 vide students of chemistry with a course in German which will 

 serve as an aid in reading the German literature of this science. 

 Students of German, however proficient they may be in the 

 classical literature of the language, find difficulties in mastering 

 the German scientific nomenclature and such difficulties are in- 

 creased by the lack of dictionaries giving correct meanings of 

 scientific terms. 



Many textbooks on Scientific German have appeared, but it has 

 become common in the planning of such textbooks and in the 

 teaching to regard Scientific German as a subject that could be 

 taught and studied rather remotely from the sciences concerned 

 in the student's plan of work and, in attempting to cover the entire 

 scope of the various sciences entering into University curricula, 

 the fact has to some extent been overlooked that the German 

 nomenclature of a single science should be studied by the student 

 more systematically and in greater detail and after he has become 

 sufficiently advanced in the science to grasp the meanings of 

 technical terms and to understand their uses. 



Of the various sciences none is more indebted to the Germans 

 for its past and present development than chemistry and the 

 student of advanced chemistry is preeminently in need of a 

 knowledge of German sufficient to enable him to read the best 

 German chemical literature. There is need for a standardizing of 

 the courses in Scientific German. When this is secured it will 

 probably be required that the student should have definite know- 

 ledge of the German nomenclature of the particular sciences in 

 which he is partially specializing. For the attainment of a 

 standard of teaching there is need for textbooks upon the German 

 of particular sciences. 



The present book is a contribution to that portion of Scientific 

 German which deals with chemistry. It contains rules of no- 

 menclature interspersed with exercises intended to illustrate the 

 use of German terms pertaining to general chemistry, inorganic
