316 MR C. G. WILLIAMS ON THE VOLATILE BASES 
through nine perfect fractionations, at the end of which a base was obtained, if 
not absolutely free from the more highly carburetted bases, at least so nearly, 
that, on analysis— 
5+265 grains of base, boiling between 320° and 330° F. (160°-165° C.), gave 
15190... ~—_ carbonic acid, and 
4-040 ... water,

This, then, is the third occasion in which lutidine has been observed, the other 
two being, first, in bone oil, where it was discovered ;* and, secondly, among the 
bases produced by destructive distillation of the bituminous shale of Dorsetshire, 
where I found it among others of the same series.+ 
The analysis of the base from those sources yielded the numbers following, 
where they are compared with the same base from cinchonine.

Before converting the fraction which gave the analysis mentioned above into 
platinum salt, in order to confirm the result, it was once more distilled, that portion 
only being received which came over between the same points; the double salt 
then obtained gave the following numbers :— 
9-025 grains platinum salt, boiling between 320° and 330° F, (160°-165° C,), tenth rec- 
tification, gave P 
8-915 ... carbonic acid, and 
2°730 ... water. 
5°715 grains platinum salt gave 
1-780 ... platinum,
