Products of the Decomposition of Picoline. 
Action of Chlorine on Picoline—The action of a current of chlorine on pico- 
line, both dry and dissolved in water, has been already described, and the results 
were not such as to induce further experiments in this way. But when an excess 
of picoline is projected into dry chlorine gas, it is rapidly converted into a more 
or less distinctly crystallized mass, which, when treated with water, leaves a 
quantity of an amorphous powder of dazzling whiteness. The properties of this 
substance are so like those of the corresponding pyridine compound, that the same 
words would almost serve to describe it. It is insoluble in water; but alcohol dis- 
solves it easily, and the solution, when boiled, undergoes decomposition ; an ethe- 
rial odour, not unlike that of hydrochloric ether, and probably due to the forma- 
tion of that substance, is first produced, and that is followed by a pungent vapour. 
It is insoluble in the dilute acids, but soluble in concentrated nitric acid. Potash 
decomposes it in the cold, and more rapidly if heated. Heated on platinum, it 
gives off a very pungent vapour and leaves a bulky charcoal. It is decomposed 
when heated in the water bath. The portion used for analysis is dried 7m vacuo. 
The results were,— 
6:170 ... carbonic acid and 
5°550 grains dried in vacuo gave 
1100 ... water. 
eae grains burnt with lime gave 
9-265 ... chloride of silver.
