68 ON SOME PRINCIPLES OP WHITE CINNAMON. 
part of the oil distilled floated on the water, but there finally 
passed over an oil which sunk to the bottom of the vessel. 
So small a quantity of this heavy oil was obtained, that 
only one analysis of it could be made, which was defective. 
This oil had a peculiar odor, not comparable with another 
oil. It was not possible to combine it with potassa. 
The solution of potassa, from which the oil had been ex- 
tracted by distillation, was separated by filtration from a 
small quantity of a deep brown semi-resinified oil, which 
also floated on the surface ; it was then saturated with 
sulphuric acid, it became milky and was afterwards dis- 
tilled. There was obtained, but in small quantity, an oil 
heavier than water, sufficiently characterised by its odor 
resembling oil of cloves (caryophillic acid.) It easily and 
completely dissolved in potassa, and was again separated 
from it by the acids. 
The light oil, which formed the greater part of the whole 
oil, greatly resembled in odor, oil of cajeput ; it was sub- 
mitted with water to a fractioned distillation. 
The portion which first passed over boiled at 356° F. 
It contains in 100 parts : — 
Carbon, - 75.25 
Hydrogen, - 11.28 
Oxygen, ... - 13.46 
Another portion of this oil was distilled alone and very 
slowly in an oil bath of the temperature of 330° F. until 
about half was distilled over. It presented the following 
composition: — 
I. II. 
Carbon, - - - 79.12 79.09 
Hydrogen, - - 11.58 11.71 
Oxygen, - - - 9.30 9.20 
The portion of oil which came over last was by fractioned 
distillation with water, and whose odor likewise greatly re-
