 of the total nitrogen belonged to albuminoids.

In their second paper,* the same authors showed that 

 among the amide-like bodies contained in beets was gluta- 

 min, and a triflnig amount of asparagin. They also in- 

 vestigated the functions of the amides, with the reaults 

 already stated on page 37. 



A considerable amount of non-albuminoid nitrogen has 

 also been found in the potato by Sehulze & Marcher + 

 and by Kreusler,:}: and more recently Schuke & Barbieri ^ 

 have publislied more extended investigations of five sorts 

 of potatoes, which showed that the nitrogen of the fresh 

 substance was distributed as follows :
