temperatures over sulphuric acid, and when it had reached a syrupy 
consistence it slowly solidified into a mass of fine needle-shaped 
crystals, which were the hydrochlorate of a new base, to which I 
give the name of Phosphaniline. 
The crystals were well pressed between folds of filter paper, and 
then being placed on a filter, were washed with a very small quantity 
■ of alcohol and ether ; again dissolved, and evaporated as before, the 
crystals were pure. The substance so obtained dissolves easily in 
water, alcohol and ether, and is neutral to test-papers. G-ently heated, 
it sublimes, and gives fine prismatic crystals. Treated with solu- 
tion of potash it is decomposed. Strong sulphuric acid expels 
hydrochloric acid, and gives a colourless solution. Nitric acid 
oxidises it, and gives a coloured solution. 
On analysis, it yielded the following results

This analysis shows that the substance is produced by the direct 
union of the chloride of phosphorus and aniline. It is, however, 
a hydrochlorate, and is formed from three equivalents of aniline, 
in which three equivalents of hydrogen are replaced by phosphorus;

Platinocliloride of Phosphaniline . — A portion of the original salt 
was dissolved in water, the solution acidified with hydrochloric acid, 
and bichloride of platinum added, in a short time crystals began to 
appear ; these, after a sufficient quantity had formed, were placed 
on a filter and washed with a small quantity of alcohol and ether, 
and dried over strong sulphuric acid, until their weight was con- 
stant. They were in the shape of small granular crystals of a light 
yellow colour, soluble in alcohol and water, but not in ether. On 
analysis, the following numbers were obtained
