chloride, the carbon entering as a biatomic molecule into the complex 

 atom. The new body would thus become a triamine, 



C." 



It is however more probable that the carbon replaces in the form of 

 cyanogen, when the new compound appears in the light of a diamine, 



as

 Cyan-triphenyl- diamine (C 12 H 5 ) 3 V N 2 .

The new compound thus becomes closely allied to melaniline, which 

 may be viewed as diphenyl-cyan-diamine,

It deserves to be noticed, that in its appearance, and in its general 

 characters, cyan-triphenyl-diamine resembles melaniline in a re- 

 markable manner. 



If we are entitled to view the new body which forms the subject 

 of this note as a cyanogen-substitute, we have not less than four well- 

 defined diamines of the phenyl- series.

I intend to continue the inquiry still further in this direction, and 

 propose next to examine the deportment of aniline with the so-called 

 protochloride (C 4 C1 4 ) and sesquichloride of carbon (C 4 C1 6 ) .
