When gently warmed with phenylamine, sulphocyanide of phenyle 

 is instantaneously converted into sulphocarbanilide, —

A similar reaction takes place with ammonia. An alcoholic 

 solution of ammonia, when gently warmed with sulphocyanide of 

 phenyle, readily solidifies into a crystalline compound, which may be 

 obtained in beautiful needles by crystallization from boiling water. 



The new bod}"^ is formed according to the equation

Sulphocyanide Sulphophenyl- 



of phenyle. carbamide. 



This substance is the thiosinamine of the phenyle-series ; like the 

 latter, it possesses the characters of a weak base. I have not been 

 able to obtain saline compounds with hydrochloric and sulphuric 

 acids. It forms, however, compounds with nitrate of silver and 

 bichloride of platinum. The latter has the usual composition, 

 viz, — 



CjjH,KS„HCl,PtCl. 



Boiled with nitrate of silver, the new compound loses its sulphur, 

 which is replaced by oxygen, phenylcarbamide, CuH^N., 0.„ being 

 produced, a substance whicli I described many years ago. Sulpho- 

 cyanide of phenyle is acted upon by a great number of ammonias, 

 with formation of bodies the composition of which is sufhciently 

 pointed out by theory. 



The mode of producing cyanate and sulphocyanide of phenyle, 

 whicli I have described in the preceding ])aragraphs, deserves some 

 notice, since the usual processes suggested by the experience in the 

 methyle-, etliylc- and amyle-series, sucli as distillation of sulpho- 

 phenylates with cyanates and sulphocyanides, have altogether failed 

 in producing the desired result. The same reaction may be of
