Zincochloride of Fhosphaniline. — Hydrochloric acid was added 

 to a portion of the solution of the hydrochlorate in water, and then 

 some fragments of pure zinc were thrown in. After the zinc had 

 dissolved the fluid was evaporated at a gentle heat (about 200° 

 Fahr.), and filtered from a few greenish flakes which had formed, 

 as even that low temperature appears to decompose the salt. The 

 clear fluid was then put over sulphuric acid and left for some days, 

 when crystals of a zinc salt were obtained, but under the same 

 conditions as the hydrochlorate, as the solution was very concen- 

 trated before the salt appeared, and then it solidified completely. 

 The crystals were pressed between folds of filter paper, and washed 

 with a mixture of alcohol and ether, and dried in vacuo over strong 

 sulphuric acid. They were white needles, slightly deliquescent, 

 and soluble in alcohol. In ether it, does not dissolve, but it 

 becomes liquid, having the same appearance as a drop of oil in 

 water.

Bromine water immediately precipitates a brownish-coloured 

 substance from an aqueous solution of the hydrochlorate. This 

 precipitate was washed with water, and a portion of it boiled for 

 some time, and found to be insoluble in water; but a substance 

 appeared to have volatilized along with the vapour of the water, as 

 the neck of the flask and a glass rod which was held over the 

 mouth of it were covered with white feathery crystals. The fluid 

 was filtered, and, after drying the brown residue, it was put into a 

 beaker covered with filter-paper, and left over a water-bath, when 

 it nearly all sublimed in crystals corresponding to those obtained 

 when attempting to dissolve it. A few of these crystals were dis- 

 solved in alcohol and bichloride of platinum added, but no preci- 

 pitate was formed, and on evaporation the original substance 

 crystallized out. These circumstances indicated the body to be 

 Tribromaniline. The filtrate from the brown substance obtained 

 originally was treated with bichloride of platinum also, but no pre- 

 cipitate forming, it was presumed no bromaniline or bibromaniline 

 had been formed. 



Cadmium Salt. — Chloride of cadmium gives, with strong solutions 

 of the hydrochlorate, scaly crystals of a double salt, moderately 

 soluble in water. 



Copper Salt. — On adding chloride of copper to a solution of the 

 hydrochlorate, and evaporating over sulphuric acid, small granular 

 crystals of a beautiful green colour are obtained. 



Mercury Salt. — If a strong solution of chloride of mercury is 

 added to a concentrated solution of the hydrochlorate, beautiful 

 white scaly crystals precipitate out immediately ; but if the solu-
