430 A Treatise on 
is from 9j. to sj. The Oil by repeated Diftilla- 
tions, either with Quick-lime or Water, lofes its 
foetid Smell, and becomes agreeable. Internally it 
provokes Sweat. Txternallydt powerfully refolves 
Tumours, is ferviceable againft the Rheumatifm 
and Palfy, and is commended againft Difeafes of

2. A fixt Salt •, which is made by calcining Tar- 
tar in an open Fire, or alfo the Refiduum after the 
Spirit and Oil are drawn off. This fixt Salt of Tar- 
tar is an extremely acrimonious and cau flick Alkali : 
Wherefore it is feldom ufed inwardly, though fome 
account it diuretick. In many chymical Operations 
it is very ferviceable ; particularly in drawing Tinc- 
tures from refinous and fulphureous Compounds. 
Sometimes it is mixed with Purgatives, as well to 
unfold their fulphureous Parts, as to help their Ac- 
tion by attenuating the Humours. It is prefcribed 
from gr. xij. to ^fs. but ought always to be dif- 
folved in a large Quantity of Water, left its Acri- 
mony fhould hurt the Membranes of the Throat 
and Stomach. If it be fet in a damp Place, it runs 
in a fhort Time, by the Moifture of the Air, into 
a Liquor, which is called Oleum SCartari per Deli- 
Guium. Moreover, from Salt of Tartar is drawn a 
Tincture by the Means of Spirit of Wine, which 
fome greatly commend. It contains, fome of the 
alkaline Parts of the Salt, with fome oily ones ; 
and therefore is proper to incide vilcid and tenacious 
Humours upon the Coats of the Stomach, in the 
Kidneys, or Glands of the Mefentery. It is given 
in any fuitable Vehicle from gutt. x. to xxx. It 
likewife ferves to extract fulphureous and oily Tinc- 
tures from Vegetables and Minerals. 
3 . A volatile urinous Salt ; which is drawn either 
from Tartar, moiftened and fermented ; or from 
the Lees of Wine j or from the fixt Salt of Tar- 
tar
