Acids change blue, purple and green
coors Of vegetable into red; and neu,
tralize aklies and earth. The eIemen-
try principle is oxygen. There are
eighteen mineral acids, nine vegetable,
and five animal.
Alkalies lave the power Of changing
the blue vegetable juices TO green and
yellow, the yellow to orange, the orange
TO red. and the red to purple. Acids
change vegetable blues to red. Chlo-
rine destroys all colours.
Allnmina is the chief constituent OF
clay;' it combines with lime, and hence
The use Of lime in iron stone.
Lime is obtained by burning parts
of rock and mountains which are often
composed Of it. Wien. burnt it is
corrosive, and tingrs blue vegetable

This is the cause of the heat which
accompanies the slackiGg of lime ;
