On the Action of Bromide of Ethylene upon Aniline. 69 

 able composition 



Treated with oxide of silver, the solution of the iodide yields a power- 

 fully alkaline liquid, possessing all the characters of the class of 

 bodies of which hydrated oxide of tetrethylammonium is the type. 

 On adding hydrochloric acid and bichloride of platinum, this liquid 

 furnishes a pale yellow amorphous platinum-salt containing

A repetition of this experiment in the ethyle-series has given perfectly 

 similar results. On account of the less powerful action of iodide of 

 ethyle, the reaction requires longer digestion. The iodide formed is 

 less soluble in boiliug water than the corresponding methjde-com- 

 pound, and therefore more difficult to separate from any cthylene- 

 phenylaminc which may have remained unchanged. When pure, the 

 new iodide is a yellowish white substance crystallizing in needles. 

 It fuses in the water-bath without decomposition to a yellow oil, 

 which solidifies on cooling into a brittle crystalline mass. 



On analysis, numbers were obtained corroborating in cver^' respect 

 the results furnished by the methyle-series. The iodide contains

Like the methyle-compound, it is readily decomposed by oxide of 

 silver; and the powerfully alkaline solution yields, with hydrochloric 

 acid and bichloride of ])latinum, a salt of exactly the same appear- 

 ance as the salt of the methyle-series. This platinum-salt was found 

 to contain

The action of iodide of methyle and ethyle upon ethyleue-pjienyl- 

 amine, although different from what might have been anticipated, 

 nevertheless appears to fix in an unequivocal manner the state of 

 substitution of this base. It is obvious tbat cthylcne-j)henylamiiic no 

 longer contains any replaceable hydrogen, and consequently that the 

 molecule (C, HJ", equivalent to 11, as such, has been assimilated by 

 tlic aniline. 



lint how is the composition of the bodies formed by the action of 

 iodide of methyle and ethyle to be interpreted? Are they simply 

 compounds of tlic alcohol-iodides with 2 ccpiivalcnts of ethylene-plie- 

 iiylamine, analogous to the .salts jjroduccd by the union of 1 cquiv. 

 iodide of mercury with 2 e(iuivs. of ammonia? 



D(jes not tlie existence of these bodies involve a further considera-
