And, it alfo follows, that the earth fepara- 
ted from lime-water by an alkali, is the 
lime which was diffolved in the water now 
reftored to its original mild and infoluble 
{tate. 
Ill. Ir it be fuppofed that flaked lime 
does not contain any parts which are 
more fiery, active, or fubtile than others, 
and by which chiefly it communicates its 
virtues to water; but that it is an uniform 
compound of lime and water; it follows, 
that, as part of it can be diflolved in wa- 
ter, the whole of it is alfo capable of be- 
ing diffolved. : } 
IV. Ir the acrimony of the cauttic al- 
kali does not depend on any part of the 
lime adhering to it, a cauftic or foap-ley 
will confequently be found to contain no 
lime, unlefs the quantity of lime employ- 
ed in making it were greater than what 
is juft fufficient to extract the whole air 
of the alkali ; for then as much of the fu- 
_ perfluous quick-lime might poflibly be 
diffolved by the ley as would be diffolved 
: _by pure water, or the ley would contain 
as much lime as lime water does.
