Diethylsincamine. 



This body is produced by the action of zincethyl upon diethyl- 

 amine. The reaction requires to be aided by heat. Pure hydride of 

 ethyl is evolved, and the following equation expresses the reaction : 





Its reactions are quite similar to those of the bodies above 

 described.

Dry oxamide and pure zincethyl are without any action upon each 

 other at ordinary temperatures, but the heat of a water-bath is suffi- 

 cient to establish a violent reaction, torrents of pure hydride of ethyl 

 are evolved, and zincoximide .combined with zincethyl remains in 

 the retort. The following equation expresses the reaction :

Acetamide and zincethyl act upon each other very violently ; a 

 large quantity of gas is evolved, which analysis proves to be hydride 

 of ethyl. Zincacetimide is contained in the residue as a white, amor-
