The second rectification of 100 cc. of the crude oil gave the 
following results :— 
Fraction distilling between’ 170°3 — 172:4° C. = 187 
” ” ” 172°4 — 1776 = 43 
” ” ” 177°6 — 182°8 = 18 
” ” ” 182:°8 —_ 193°2 = 8 
” ” ” 266°7 — 272-0 = 9

The first three fractions entirely evaporated when placed in 
watch glasses; the fourth contains a small quantity of resinous 
bodies which prevents entire evaporation of this fraction and yet. 
shows no signs of any crystalline body. 
(d) A new Soutip CampHor OR STEAROPTENE. 
The fifth fraction forms well marked crystals on the slow 
evaporation of those portions which are volatile in the air, so that 
we shall have little difficulty in obtaining the crystallised sub- 
stance in this way, provided we do not succeed in isolating it by 
an easier method. It was not possible to crystallise it out from 
its fraction by freezing at a temperature of 10° below zero. 
We were first attracted to this new substance by detecting its 
presence as a white crystallised body around the cork of the bottle 
in which the oil was placed, as well as on wooden benches on 
which it had been dropped. No method has so far been found to 
completely separate it chemically from its fraction. The best 
method whereby we have obtained the crystals is to saturate 4 
large cork with the oil, when after some days the camphor erystal- 
lises out upon the surface as seen on the specimens submitted.
