The fluid from which the iodine had been preci- 
pitated was treated with hydrochloric acid in excess, 
the chloride of silver removed by filtration, and the 
fluid evaporated to a moderate bulk, excess of bi- 
chloride of platinum was then added, and the pre- 
|__| cipitated platinum salt washed, first with a little 
water, and then with a mixture of alcohol and ether. The platinochloride of amyl- 
chinoline is only sparingly soluble in water, it was dried at 212°, and burnt with 
chromate of lead and copper turnings.

Action of Chlorine on Chinoline.—According to GrrHARDT,* chlorine converts 
chinoline into a black resin, but my experiments show that it acts in a very dif- 
ferent manner, if care be taken to prevent rise of temperature. On dropping 
chinoline into a large glass vessel of the gas, and leaving it for twelve or fourteen 
hours, a yellow oil is produced, which, on treatment with water, leaves a white 
insoluble matter, which I have not yet had an opportunity of studying more in 
detail.
