Analjfis of the Atr. 2 85 ? 
fermentation is (he fays) the motion of 
the air intercepted between the fluid and 
vifcous parts of the fermenting liquor 
but the caufe of putrefaftion is fire it 
felf, collefted or included within the 
putrefying fubjeft, Trocefs, 77.” But I do 
not fee why thefe may not reafonably 
nough be looked upon as the effefts of dif- 
ferent degrees of fermentation 5 nutrition 
being the genuine efFeft of that degree of 
it, in which the fum of the attradling ac- 
tion of the particles is much fuperior to 
the fum of their repulfive power : But when 
their repelling force far exceeds their attrac- 
tive,, then the component parts of vegeta- 
bles are diflblved. Which diflbiving fubftances, 
when they are diluted with much liquor, do 
not acquire a great heat in the diifolutionj 
the brisknefs of the inteftine motion being 
checked by the liquor : But when they^ are 
only moift, like green and damp Hay, in a 
large heap, then they acquire a violent heat,- 
fo as to fcorch, burn and flame, whereby 
the union of their conftituent parts being 
itiore throughly diflblved, they will neither 
produce a vinous, nor an acid fpirit : Which 
great degree of folution may well be effefted
