This ftone fometimes readily, at other 
times only when rubbed, fmells like the he- 
par fulphurisy or gun-powder. It excites no 
effervefcence with acids, and is a medium 
between the gypfum and the foetid ftones of 
the laft fedion, to which it has, however, ge- 
nerally been clafled, although no lime can be 
made from it *, whereas they are the fitteft of 
all the different limeftones to be burnt in- 
to lime. It is found

* The method that Nature takes in combining thofe mat- 
ters which compofe the liver-fione, may, perhaps, be the 
fame, as when a lime-ftone is laid in a heap of mundic, while 
it isroafting ; becaufe there the fulphur unites itfelf with the 
lime-ftone, whereby the limeftone acquires that fmell com- 
mon to liver of fulphur, inftead of which the vitriolic acid 
alone enters into the formation of gypfum. How the ful- 
phur combines itfelf may likewife be obferved in the flate- 
balls or kernels from Andrarum alum mines, where it 
fometimes combines itfelf with a martial earth, of which 
this date abounds, and forms therewith pyrites within the 
very Hate-balls. 1 have called this fpecies the Liver Hone, 
notwithftanding that name, by reafon of irs colour, has be- 
fore perhaps been given to feme other kind ; but as (in my 
opinion) the colour is a circumftance of very little or no im- 
portance in mineralogy, fo as not to deferve to be taken no- 
tice of, in preference to other chara^lers of more confequence, 
I hope my boldnefs herein will be excufed. The foetid or 
fwine-ftones, and the liver-ftone, are, in regard to the Itrudure
