macopoeial requirements. It is interesting to note that the new 

 revision of the new Japanese Pharmacopoeia will also be published 

 in Eng-lish and possibly in Latin or some European language. 



The Colleges of Pharmacy are opening their sessions this month, 

 and many young men and women will enter upon the work which is 

 expected to prepare them for their life's calling. We desire to 

 impress upon them the advisability of making the best posible use 

 of their time. The seven or more months of study will soon be 

 over and then it is too late to profit by opportunities which were 

 neglected. Realize that the information gained will be of use to 

 you during your entire life which is to follow. — M, B. Druggist. 



THE NATURE OF ADRENALIN. 



Adrenalin is among the substances considered by the Phar- 

 mazeutische Post (March 3. 1907) in its instructive review of the 

 progress made in pharmacological science during the year 1906. 

 The latest word on the question of the constitution of adrenalin 

 comes from E. Friedmann, wdio gives as the formula CcH3(OH)o 

 :CHOH iCHoNHCHs. Concerning the source of adrenalin in the or- 

 ganism, Friedmann considers that certain albuminous bodies, such 

 as oxyphenylserin or oxyphenylmethylserin, represent the mother 

 substance. These substances on oxidation may become adrenalin 

 acid, and further changes brought about by fermentation and re- 

 sulting in the throwing ofif of carbonic acid give rise to the ad- 

 renalin. W. L. Halle considers tyrosin and phenlalanin the most 

 important elements iu the formula of adrenalin from the fresh 

 glands, and in a number of cases he was able to demonstrate an in- 

 crease in the amount of adrenalin, while in others no such increase 

 was found. Finally, mentions is made of the efifect on the glycogen 

 of injections of adrenalin. Z. Gatingruzewska has shown that if 

 adrenalin is injected into the peritoneal cavity of guinea pigs in 

 the proportion of i "Mg. of adrenalin to i Kg. body weight, and the 

 animal is killed 36 to 40 hours after the injection, there will be 

 found a complete disappearance of the glycogen in liver and muscle. 

 This is the most effective way of rendering an animal glycogen 

 free.
