THE BIOCHEMICAL BULLETIN 



The BiocHEMiCAL Bulletin is a quarterly Journal of bio- 

 chemical notes and news. It publishes results of original investiga- 

 tions in chemical biology and presents miscellaneous items of per- 

 sonal and professional interest to biological chemists. 



Biological chemists everywhere are cordially invited to forward 

 contributions of any character whatever that will increase the value 

 and add to the interest of the Bulletin. Original contributions 

 to research, preliminary reports of investigations, abstracts of 

 papers, addresses, reviews, descriptions of new methods and appa- 

 ratus, practical suggestions to teachers, biographical notes, histori- 

 cal summaries, bibliographies, quotations, news items, personalia, 

 and views on current events in chemical biology, are especially 

 solicited. 



The Bulletin will present as much biochemical substance of as 

 great variety and value, in as little space and at as small an annual 

 .subscription price, as possible. Contributors are accordingly re- 

 quested to keep their papers within the bounds of 15 printed pages, 

 if possible, and to restriet them to 10 pages or less, if it can be 

 done satisfactorily. Recrystallize the products repeatedly, reject 

 the mother liquors and send the Biochemical Bulletin " prepa- 

 rations of tested purity" ! 



Each volume of the Bulletin will contain about 500 pages. 

 The price of one volume, sent postage free to subscribers in the 

 United States and Canada, is $2.75 ; to subscribers in other coun- 

 tries, $3.00. The reserve supply of copies of the initial number of 

 the Bulletin has nearly been exhausted. The future price of the 

 first number of the Biochemical Bulletin, to all but subscribers, 

 will be $1.50. 



Remittances, manuscripts and other Communications may be 

 addressed to the Biochemical Bulletin, 437 West 59th St., New 

 York.
