The above numbers show the slight excess of carbon which 

 often occurs with the substitution products of hyponitric acid, 

 especially when the combustion is carried on rather quickly. 

 Unfortunately we had no more of the base to prepare this 

 salt again, but there is little doubt but that the analysed salt 

 corresponds with the binoxalate of chloraniline*. 



Double Salt of Hydrochlorate of Nitraniline and Bichloride 



of Platinum, C 12 -j j^ >N, HC1, Pt Cl 2 . — An aqueous so- 

 lution of hydrochlorate of nitraniline is not precipitated by 

 deutochloride of platinum ; but when an alcoholic solution 

 of the former is mixed with the latter, a yellow crystalline 

 double salt is formed, which is exceedingly soluble in both 

 water and alcohol, and therefore must be washed with ether. 

 We have already alluded to the determination of the platinum 

 in this salt when treating of the atomic weight of the base. 

 We append the calculated composition of this salt along with 

 the platinum per-centage found.

We have not examined the other salts of nitraniline. 



Products of the Decomposition of Nitraniline. 



We have not as yet made many experiments in this direc- 

 tion, owing to the great difficulty of obtaining the base in 

 sufficient quantity ; we can therefore only give a few reactions. 



Nitric acid violently decomposes nitraniline, and after con- 

 tinued boiling affords an acid which we have not more closely 

 examined. There is little doubt but that it is carbazotic acid. 



When this base is treated with bromine violent action takes 

 place, accompanied by an elevation of temperature and a 

 strong disengagement of hydrobromic acid. After some time
