Aurochloride of Ethylopicoline.—This compound is readily formed, by adding a 
solution of chloride of gold to the nitrate, with excess of hydrochloric acid, ob- 
tained from the iodide, in the manner employed for the production of the plati- 
num salt. It is slowly deposited in the form of golden-yellow fiattened prisms 
of great beauty. It is sparingly soluble in cold water, readily in hot, and is de- 
posited unchanged on cooling. It is insoluble in alcohol and ether. Ammonia 
converts it into a cinnamon-brown powder, and it is instantly blackened on the 
addition of potash to its hot solution. The specimen analysed, was dried at 212’, 
and burnt with chromate of lead.

It has been already mentioned that, though behelopicalines is fixed and inodor- 
ous, its iodide cannot be distilled with potash, or the base itself boiled or even 
evaporated in vacuo, without undergoing a decomposition, attended with the evo- 
lution of volatile base. In the latter case the decomposition is slow, and even after 
the ebullition has been continued for some hours the odour is given off with undi- 
minished intensity, till by long-continued boiling it at length becomes extremely 
faint although it does not altogether disappear. When the iodide is boiled with pot- 
ash, the change is more rapid, and after three or four hours’ boiling a considerable 
quantity of base is found in the receiver. The product has a pungent and putrid 
odour, fumes strongly with hydrochloric acid, and forms with it a salt entirely
