water bath in sealed tubes for forty hours, have not the slightest 
n on each other, — addition of a small quantity of carbon 
disulphide to the mixture so facilitates the reaction that even in 
six hours it is ees and in one case the tube exploded from 
the evolved hydrogen bromide, in two hours, Further investiga- 
tion showed that the presence of the disulphide was not abso- 
lutely necessary, ‘oie for the formation of the addition or the 
renee products of bromine and acetic acid, but that it facil- 
ted the formation of both to an extraordinary degree, the time 
required for the action to be completed being in the exact inverse 
ratio of the amount of CS, present. The precise mode of action

7. On. the Conversion of Nitriles into Amides.—Prsner and 
Kietn showed a short time ago that any nitrile may be made to 
combine directly with = alcohol, by passing gaseous HCl or 
HBr into a mixture of the two. There is first formed the salt of 
an fotiockinnne 
_RCN+R’0H-+(HCl),=RC OW HC) 
which immediately loses HCl and becomes a salt of an imide. 
Thus benzonitrile and isobutyl alcohol when thus treated give the 
hydrochlorate of benzimidobutyl ether, C.H,C | OCH, wee By 
the action of alcoholic ammonia, the free benzimidobuty] ether 
C.H C} 06, H, and benzimido-amide (or benzenylamimide) 
C.H,C HCl are obtained. The authors now describe ben- 
siidborade and its silver compound, and the action of ethyl 
iodide and of acetic oxide u upon it, and also benzimidobutyl ether.
