The extreme heat of the weather, (the thermometer
being at eighty-six upon the 19th of August, 1820,)
rendering it probable that part of the loss of weight
arose from evaporation, the same mixture was
exposed the following day at the same hour, and
for the same length of time, after the efferves-
cence had completely ceased, and under every
other circumstance similarly to the experiment
of the day before : 10 grains were lost by evapo-
ration solely.
Probable loss by the expulsion of the carbonic acid,
87 grains—giving 193| grains of carbonate of lime.
C. The insoluble part floated in the mixture in
shreds ; washed and dried, weighed 6 grains.

SANTA MAURA.
Experiment, No. 6.
Rock of which El Vouno Mountain, and Diamigliano,
being apparently the same, are composed.
Is of a rough scabrous appearance and grayish
blue colour. Specific gravity, 2.012.
A. 300 grains were dissolved in 15 drachms of di-
luted muriatic acid—lost 67 grains, contains 148f of
carbonate of lime.
B. 158 grains were collected afterwards, inso-
luble. The surplus probably originating in the mat-
ter not having been sufficiently washed, or dried, or
some other small error in the manipulation. Pro-
bable amount of the insoluble part, 151|.
