Strecker considers glycosin as possibly an ammonia having the

To this theory it may be objected that it does not explam the 
formation of alanin and other bodies of the same class, or the 
roducts of their decomposition. 
Laurent looked upon glycosin either as amido-acetic acid—a 
; also recently taken by Cahours—or as the acid amid of 
c acid. But Dessaignes has actually prepared glycolamid, 
shown that it is only isomeric and not identical with 
.—This body was obtained by Strecker by evaporating 
e of aldehyd-ammonia and cyanhydric acid with chlor- 
hydrie acid, and its empirical formula is CoHzNOs, so that it is 
homologous with glycosin. Its mode of formation appears to 
me to show in the clearest manner its molecular structure, and [
