this property: it appeared, 
therefore, that the camphorate 
of lime always exists with an 
excess of acid. The liquor was 
decanted, and the deposit boiled 
with eight ounces of new water; 
it was then filtered. The car- 
bonate of lime strongly dried 
weighed 57 grains: thus 50 
grains of camphoric acid re- 
quire, in order to be saturated, 
28 grains of carbonate of lime. 
The liquor was reduced to half 
an ounce by evaporation in a 
small capsule: but as it refused 
to crystallize, another drachm 
of liquor was evaporated: a 
tolerably strong pellicle was 
then exhibited: upon the cooi- 
ing of the liquor, there was se- 
parated at the end of 48 hours 
a considerable quantity of cry- 
stallized salt, but the form of 
the crystals was not sufficiently 
decided. The concentrated so- 
lution of camphorate of lime 
has not a remarkably salt or 
bitter taste; it leaves a taste 
of lime, and is a little acrid, 
which distinguishes it consi- 
derably from calcareous ben- 
zoate. 
{t must also be remarked, 
that always when this acid is 
saturated, there is a slight and 
transient smell of camphorie 
acid, of which however the li- 
quor gives no indication even 
when it is heated. 
7. Action of caloric on the 
camphorate of lime. Five 
grains of camphorate of lime 
were introduced into a phial 
with a long neck and narrow 
aperture. There was a slight 
noise, the crystals were then 
dried

been reduced to two ounces 
gave upon cooling small needlc- 
formed erystals, silky and bril- 
liant, several of which issued 
from a common centre. At 
the end of two hours the whole 
of the liquor was filled with 
these small crystals, and it fur- 
nished them to the end by eva- 
poration and cooling: the taste 
of these crystals was mild, and 
a little earthy. 
It is also proper to remark 
here, that although pure and 
white acid was employed, there 
was a slight smell of benzoie 
developed, which speedily dis- 
appeared, and which was ne 
longer remarked in the liquor,

benzoate of lime. Five grains 
of this salt, perfectly pure and 
white, treated in the same way, 
presented the following phae- 
nomena : it was perfectly liuue-
