it differs in all its properties. I propose for this new compound the 

 name of par aniline. 



Paraniline forms a series of splendidly crystallized salts, the study 

 of which proved that the above expression must be doubled, and that 

 the true molecular value of this compound is represented by the for- 

 mula 



C U H U N,. 



The molecule of paraniline is capable of fixing either one or two 

 equivalents of acid. The salts with one equivalent of acid are most 

 readily obtained ; they are of a light yellow colour, and their solution 

 exhibits in an unusual degree the phenomenon of green fluorescence. 



From a solution in concentrated hydrochloric acid a beautiful hydro- 

 chlorate crystallizes in transparent yellow six-sided plates, containing 



at 100 



C 12 H U N 2 ,2HC1+H 2 0, 



which on treatment with water are immediately converted into yellow 

 needles sparingly soluble in water, more soluble in alcohol, insoluble 

 in ether, containing 



C 12 H 14 N 2 ,HC1 + H 2 

 at 100, and 



C 13 H U N 2 , HC1 

 at 115. 



The platinum-salt crystallizes in yellow difficultly soluble needles, 



C 12 H 14 N 2 , HC1, PtCl a (atllO). 



I have analysed only one nitrate, which crystallizes in short, yellow- 

 ish, starlike-grouped needles, containing 



C 12 H U N 2 , HN0 3 , 



but two sulphates. One of them is readily obtained by dissolving 

 paraniline in dilute sulphuric acid, when spherical aggregates of small 

 needles are separated, easily soluble in water, less soluble in alcohol, 

 which have the composition 



C 12 H M N 2> H 2 S0 4 . 



Digested in aqueous solution for some time with an excess of 

 paraniline, the sulphate just described assimilates a second equi- 

 valent of the base, a salt being formed very similar to the previous 

 one, but containing after crystallization from alcohol 



2(C la H I4 N 2 ),H 2 S0 4 .
