from the Tartar^ to which Vinegar owes 
its acidity, as from the diffolvcd Oyfterfliell. 
And what makes it further probable is, that 
the Vinegar lofcs its acidity in the ferment, 
that is its Tartar : for dilfolving menftruums 
are generally obferved to be changed in fer- 
mentation, as well as the diilblved body. 
Have we not reafon alfo hence to con- 
clude, that the energy of acid fpirits may in 
fome meafure be owing to the ftrongly at- 
tracling air particles in them 5 which aftive 
principles may give an impetus to the acid 
fptcul^y as well as the earthy oily matter, 
which is found in thefe acid fpirits? 
There are we fee alfo great fiore of air 
particles found in the Analyfis of the blood, 
which arifes doubtelefs as well form the feriim 
as from the craff amentum, for all the animal 
fluids and folids have air, and fulphur in
