solves it readily, i if the solution be evaporated a residue is obtained 
nearly insoluble in water and apparently identical with cyanuramid ; 
cyanamid is also soluble in alcohol and ether without change, but al- 
kalis decompose it; with acids it gives crystalline compounds not yet 
examined. ‘The volatile bases of Wurtz, and many other organic al- 
kalies yield similar compounds when treated with chlorid of cyanogen 3 
the authors have obtained cyano-methylamid, cyanethylamid, and cy- 
anamylamid, represented by the formulas, Cy 2H,N, Cy C,H,N,

scribed, aeither is it stated whether there exists a class of isomeric cya-

6. Aldehyde of Caprinic Acid.—Wacnen has studied the action of 
ammonia upon the oil of rue, which the researches of Gerhardt an 
Cahours had shown to consist principally of -an oxygenated oil having 
the formula C,,F,,0, and capable of being readily converted by oxy: 
dation into caprinic acid, C,,H,,0,. When oil of rue 1s
