526 Helpful Books in Biochemistry [Mar. 



latest English presentation of Olof Hammarsten's Text-book has 

 beeil referred to elsewhere. Aside from personal differences of 

 opinion in regard to a few things, it seems that the treatment is such 

 as to appeal to all students and investigators. If such workers will 

 not go to original sources and to such finished products as those of 

 Höber, Freundlich and others, published in foreign tongues, they 

 may well find a resume in Hedin which has a modern touch. 



A digest of certain phases of the subjects referred to above is 

 made by MacClendon in the Biological Bulletin for February, 191 2 

 (22: 113). The article is suggestive of certain lines of research 

 which may profitably be carried out. 



Mention may be made of the General-Register of the Biochem- 

 ische Zeitschrift (Volumes 1-30) which places the wealth of this 

 Journal in a form available to the reader. At the same time, it is 

 a favorable commentary on the growth of the science and speaks 

 ably against the views held by some who are unable to appreciate 

 biochemistry as a science.

In the Propaganda for Reform Department of this issue are 

 given the results of an investigation carried on in the Associa- 

 Not a Square deal tion's laboratory to determine whether or not 

 for the physician there is any chemical difference between acet- 

 phenetidin and phenacetin. As every physician knows, phenace- 

 tin was for some years the proprietary name of the substance 

 known, chemically, as acetphenetidin. When the patent on phen- 

 acetin expired, the substance became public property. Never- 

 theless, the original patentees, the Farbenfabriken of Elberfeld 

 Company, still list and seil the product under its proprietary 

 name and also offer it under its chemical name. Under the pro- 

 prietary name, the Company demands more than five times the price 

 it asks for the same product sold under its chemical name. The 

 same anomaly is perpetuated in the United States by the only 

 American firm that makes the product under both its proprietary 

 and its chemical names — Lehn and Fink. Other American phar- 

 maceutical houses seil the substance only under its official name. 

 The investigations of the Association's chemists show that the only
