represented by the formula C'® H'*+H?Q, or by 1 atom of dadyle 
and 1 water.— Oil of cinnamon. 'The distillation of the bark of the 
Laurus Cinnamonium, aided by a solution of marine salt, gave two 
oils, one lighter, the other heavier than water. ‘The oil of cloves of 
commerce is a mixture of these twooils. It boils at 220°; at 25°C. ; 
its sp. gr. is 1.008; treated with caustic baryta it is divided into two 
unequal parts ; the smaller is converted into resin, and the larger 
forms with a base a salt soluble in water. It seems therefore to con- 
sist, like the oil of cloves, of two other oils, one acid, and the other 
not acid. 0.542 of this rectified oil gave 1.596 carbonic acid, and 
0.375 water, in 100 parts, 81.44 carbon, 7.68 hydrogen, and 10.88 
oxygen.— Oil of juniper. Juniper berries distilled before they are 
ripe, with the addition of saline water, gave two oils. Purified by 
washing with saline water, and by repeated distillations from lime, 
these oils have the common characters of being easily oxidized in 
the air, and of dissolving in every proportion in absolute ether; and 
of being but slightly soluble in alcohol of 33° B. They differ also 
in some characters; the first is colorless, sp. gr. 0.8392 at 25° C., 
boils at 155° ; the solution when mixed in equal volumes with rec- 
tified alcohol is clear, but is made thick by the addition of a new 
quantity of alcohol: the second is colored, sp. gr. 0.8784 at 25° C., 
and boils at 205°. 0.349 of the first, analyzed by the oxide of cop- 
per, gave 1.116 carbonic acid. and 0.362 water. 0.551 of the sec- 
ond gave 1.748 carbonic acid, and 0.575 water. ‘Their composition

The oil of the juniper berries when ripe and preserved does not sep- 
arate into two parts; and as it possesses the properties of the second 
oil contained in the unripe berries, it appears to have been deprived 
of the first by desiccation.—J0.
