ON THE OCCURRENCE OF CREATININ IN 
LEGUMINOUS SEEDS. 
By 
K. Oshima and M. Ariizumi. 
INTRODUCTORY. 
Creatinin is found in muscles and bloods of animals in varying 
quantities, accompanying creatin, though the former in much smaller 
quantity than the latter. In living muscles of many fishes it is present 
in a comparatively large amount. Together with creatin it forms one of 
the normal constituents of urine of mammals. 
Concerning the origin of Creatinin and its relation to creatin \'arious 
views have been adv'anced. But it is a well established fact that creatin 
when administered either per os, or sub cutan, a part of it at least, is 
excreted in urine, as Creatinin. Creatinin in food is resorbed from the 
intestinal walls and is excreted again, largely as such, in urine. Aside 
from these two sources, Creatinin seems to be produced as the result of 
metabolism in animal bodies, with creatin as its intermediate form. While 
its physiological role in animal metabolism is not yet clearly understood, 
its sources have generally been considered as wholly confined to animal 
origin. 
Though, the literature concerning the biochemistry of the animal 
organism is filled with references to Creatinin, the possibility of its occur- 
rence outside of the animal kingdom has not been investigated to any great
