RECENT ADVANCES IN PHYSIOLOGICAL 

 CHEMISTRY^ 



The enormously rapid development of 

 physiological chemistry in the last ten 

 years may be well illustrated by a consid- 

 eration of the new journals which have

 Chemical Society, June 22, 1905. 



been found necessary to publish the in- 

 creasing literature, and also by the influ- 

 ence which this department of science is 

 exerting on other sciences, particularly on 

 medicine. For twenty years the Zeit- 

 schrift fur physiologische Chemie and 

 Maly's Jahreshericht were sufficient to 

 represent the specialty, which had been 

 considered a somewhat narrow one, but 

 suddenly, and almost simultaneously, three 

 other publications were called into exist- 

 ence to keep pace with the newly aroused 

 interest. These are the Biochemisches 

 Centralhlatt, the Beitrdge zur chemischen 

 Physiologie iind Pathologie and the volume 

 on Biochemistry of the Ergehmsse der 

 Physiologie, all since 1902. 



Several causes have worked to bring 

 about this situation and the most impor- 

 tant will be touched on in what follows, 

 but at the outset two things are apparent; 

 on the one hand, there is the stimulating 

 influence of pure organic chemistry, and 

 on the other the requirements of physiol- 

 ogy and pathology for a more rational 

 ■ chemical foundation. This last factor is 

 an extremely potent one ; some of the most 

 interesting problems of physiological chem- 

 istry have been suggested by questions 

 growing out of the discussion of the mod- 

 ern doctrines of immunity and the causa- 

 tion of disease. 



It follows, therefore, that many of the 

 advances in physiological chemistry are in 

 lines which are comparatively new, but 

 there are some noteworthy exceptions and 

 of one of these I wish to speak first. This 

 is concerned with the question of protein
