AfMrtherlryalofthefaid Stones by Chymkall dijiilla- 
tion. By the fame. 
TTT T.E brought this Stone to a grofs powder^ and convey- 
V V ^^^*^ ^ coated B.etorty which coated Retort was 
kept for fbme Houres in a naked Fire, ib hot that the GMs 
melted. 
The quantity we put into the retort amounted to half an 
ounce, twenty (Jraines. The hquor that came over feems 
fCarce to alFord j or 4 drops, which looks like Spirit of Harts- 
horn rectified, and fmells much like the fame : which plain- 
ly difcovers it an Animd fuh fiance though it affords much lefs 
than th^ C dmlus H'^mams do^s: and by confequence gives 
lis a rnuch larger proportion of Capia Mqrtutm or Refidmm 
in the R^-z^f^r^: All which is very confentaneous to the nature 
of the Stoney for its Specific Gravity was much heavier than 
the i'tones are, weufuallyfind in the Humane body; and 
therefore the parts may be fuppofed more fix'd, or to con- 
fift of fewer volatile parts, fiich as are carryed over by 
Diftillation. 
We w^ighM the Remainder in the Retort and it came to 
three Drams and fifty Graines ; Ten Graines of which 
feemM to hang about the neck of the Retort in the form of a 
dirty hard baked OyL The other 20 Grainds are partly 
gone off in Vapour through the Lute, and what we find in 
the Receiver in a liquid form. 
We tryed part of this Captu mortmrn by applying Mr. 
H^^^i- ftrong ik%;^^^/to enquire whether it contained any 
Iron Particles^ but did not find any would adhere. However 
there remains yet one Tryal to be made, and that is to give 
it a much ftronger Reverberation in the Fire, and then to fee 
whether fome Particles will not prove Martial^ which may 
be done at another feafbn.
