Oil of Vitriol, did by agitation mix more equally with 
the Oils, and becanme aPulpament. 
As the Juices, which conftitute the Saliva^ do fer- 
ment upon their Mixture, To it is probable that from ' 
their Mixture and Fermentation there refults fiich a 
Tertium quid as is apt to ferment with the Bile. And 
therefore, when the Aliment has been under the Fer- 
mentation, excited by the Saliva, a fufficient time, it 
is then thrown into tht Duodemmy where it meets with 
the bilious Juice, which flows into that Inteftine from 
the Liver, from which a new Fermentation feems to 
begin ; and the Commotion of the Parts of the Aliment 
being ftill continued, does carry on the Bufinefs of Di- 
.geftion until the Food isperfe&ly concofted. Tho' it 
is probable, that this new Fermentation ferves not only 
for the more perfeil: Digeftion of the Food, but like- 
wife for the Separation of the Chyle from the feculent 
Parts. 
Neither do I by a random Guefs, and an ungrounded 
Conjecture, fuppofe that from the Mixture and Fermen- 
tation of the two Juices, which conftitute the Saliva^ 
there refulta a Matter, which is apt to ferment with the 
Bile. But to me the Notion feem'd to be confirm'd by 
an Experiment that I made. For confidering with my 
(elf that the Bile is gienerally allow'd to have much of 
a faponary nature, I made a Solution of Soap in fair 
Water, and mix*d it with the Oils of Turpentine and 
Vitriol firft put together, and from their Mixture I ob- 
ferv'd a very eafie and gentle Fermentation ^ which 
continued for a confiderable time.
