watry Matter more plentifully, but alfo becaufe 
their Urine is more highly alkalized, attenua-

by fubtilized, and rendered lefs mucilaginous 
than the Urine of thofe of a left robuft and 
more lax Conftitutionof Fibres, which is proba- 
bly a principal Reafon why Women are much 
left fubjed to the Gravel or Stone than Men. 
6 . As Fermentation breaks and diflblves the 
mucilaginous Texture of vegetable Fluids, 
fo is the like Texture of animal Fluids diffolv- 
cd in proportion to the Degree of Digeftion 
which they undergo. For as all Degrees of 
Ferment in vegetable Fluids have a Tendency 
from Vifeidity to Acidity: So all Degrees of 
Digeftion, from its firft beginning in the Sto- 
mach, thro' its whole Courfe, have a Tendency 
to Putrefaftion: But in a healthy State of an 
Animal, this Tendency is flopped at a cer- 
tain Degree, by -the fweet Emulfion of frefli 
Nutriment, without a conftant Supply of 
which, the animal Fluids would foon tend to 
a fatal Degree of Putrefaftion, and Putrefac- 
tion diilblves Vifeidities. And accordingly it 
is obferved'that Urine depofites its Tartar more 
freely to the Sides of Urinals, when it has 
ftood fome time to putrifie, and to become 
thereby
