SALT-BASE FROM BITTER ALMOND OIL. 267 



These numbers lead to the formula C21 HgN, which gives in 100 parts, — 



Carbon 85* 1 



Hydrogen 5*4 



Nitrogen 9'5 



10000 



This, which appears to be a neutral body, together with its accompanying liquid 

 product, deserves a more extended examination. 



The hope which I ventured to express in a former paper of the formation of new 

 organic bases from the volatile oils which unite with ammonia, by subjecting their 

 amides to the influence of agents, as caustic potash, capable of bringing about meta- 

 morphosis of the compound into a more stable form or forms of combination, has 

 thus been partially fulfilled. 



M. Laurent has recently announced the discovery of a new substance obtained 

 from bitter almond oil, isomeric with hydrobenzamide, possessing basic properties, 

 and corresponding in some other respects with benzoline ; it is stated however to be 

 volatile without decomposition, which is certainly not the case with that body. 

 The name amarhie was conferred upon it*. The publication of the experiments in 

 detail will probably determine the identity or separate nature of the two substances.
