CHEMICAI, GERMAN 3 



system. In the "Berichte der deutschen chemischen Gesellschaft" 

 we find Calcium, Cer, Cyan, Contact, condensieren, Silicium, 

 nascierend, direct, Acetylen, Acetyl, Aceton, etc., while in other 

 works these terms are written Kalzium, Zer, Zyan, Kontakt, 

 kondensieren, Silizium, naszierend, direkt, Azetylen, Azetyl, 

 Azeton. Should a word have a technical as well as a non- 

 technical meaning its spelling may be dependent upon its meaning, 

 i. e., it may be in accordance with either the "wissenschaftliche" or 

 the "volkstumliche Schreibweise." 



There is, therefore, as yet no common standard for the spelling 

 of German words in general. However, the "wissenschaftliche 

 Schreibweise," as used in the "Berichte," may serve as a safe 

 model for the student of chemistry. It is important to remember, 

 however, that the two systems have in common: 



1. The use of the umlaut to the exclusion of the double letters 

 Ae, ae, etc. ; 



2. The replacement of th by t in words of German origin; 



3. The use of the letter e in the verb termination -ieren: thus 

 filtrieren, reduzieren, etc. 



4. The use of the double letter 6 in place of sz among small 

 letters, the fs formerly in use to represent sz being no longer 

 permissible. 



In the exercises and rules of nomenclature given in the first part 

 of this book the "volkstumliche Schreibweise" has been followed 

 generally. 



In the articles by German authors contained in the second part 

 the "wissenschaftliche Schreibweise" is common in the case of 

 the later writings. The student will find here spellings used in 

 the current numbers of the "Berichte" and in much other recent 

 chemical literature. In the older papers, published before the 

 present movement, spellings common to both the present systems 

 are found, those of the "wissenschaftliche Schreibweise" being 

 the more common. The verb ending -iren was then generally 

 used instead of -ieren. The h was then used regularly after t 

 in the words Theil, thun, Theer, etc. A and Ae were used 

 indiscriminately as were also a and ae. The use of ss for B is
