That therefore which fetters or binds up aii the 
Serofities , or m oft fluid Parts of the Bloody and 
proves a ftrong Copula between them and the red Glo+ 
bules thereof, may be reafonably fuppofed to fetter 
or tye up the fineft Fluid of all, to wit, the animal 
Spirits with the reft, ana in the fame manner to hin- 
der their Secretion, and thereby produce Sleep, or 
fome fuch Degree of it as is above-mention’d. 
IV. As to Opium, and all the Clafs of Soporifics? 
if we compare the vifible Effects of them with 
what has been faid above of Brandy, or Spirits of 
fermented Liquors, we fhall find them much the 
fame* Opium is known to leflen or fupprefs all the 
Secretions and Excretions, and is therefore of fuch 
remarkable ufe in Fluxes, Rheums , Catarrhs , See* 
it has indeed been conceived to be a Sudorific , but 
that only in Compofition with Aromatics , as in Ve- 
nice or London Treacle \ or with f aline Bodies; as 
the Sapo Tartar eus in the PiLMatthtf io r Starkij ; 
and that too aflifted by plentiful Dilution with warm 
Sack-Whey, or fuch like Liquors, and the Addition 
of Volatile Spirits of Harfs-Horn, &c. which are 
known to thin the Blood, as Mr. Leewenhoeck' s Mi- 
crofcopical Obfervations, and the mixing of thefe vor 
latile faline Spirits with Blood , as it runs out of the 
Vein into a Porringer, do fufficiently evince. Which, 
fliews, that thefe Volatile Salts are good Correctors 
of Opium, as they break down and colliquate the 
Blood, and therefore tend to promote the ferous Se- 
cretions, which Opium by itfelf, and all diftilTd 
Spirits of fermented Liquors do retain, or reftrain 
for fome time, incorporating the Serofities with the
