CHINOLINE AND ITS HOMOLOGUES. 401 
7°921 grains platinochloride of cryptidine, after treatment with nitric

A very perceptible increase in the carbon is, therefore, obtained by the remo- 
val of the impurity rendered insoluble by means of nitric acid. 
Chinoline is, therefore, the first of a series of homologous nitryl bases, of 
which three members are now known, viz. :— 
Chinoline, F b C,H, N 
Lepidine, : : C,, H, N 
Cryptidine, - C,, H,, N 
And of which a greater number might possibly be obtained by an extension of 
the inquiry.
