Analyfis of the Air. 213 
“ ligible, by feigning the particles of air 
cc to be fpringy and ramous, or rolled up 
“ like hoops, or by any other means than 
6C by a repulfive power/' The truth of 
which is further confirmed by thefe Expe- 
riments, which fhew the great quantity of 
air emitted from fermenting bodies 5 which 
not only proves the great force with which 
the parts of thofe bodies mu ft be diftended $ 
but fhews alfo how very much the parti- 
cles of air mu ft be coiled up in that ftate, 
if they are, as has been fuppofed, fpringy 
and ramous. 
To inftance in the cafe of the pounded 
Apples which generated above 48 times 
their bulk of air > this air, when in the 
Apples, muft be comprdfed into lefs than 
a forty-eighth part of the /pace it takes up, 
when freed from them, and it will con- 
fequently be 48 times more denfe* and 
fince the force of comprdfed air is propor- 
tional to itsdenfity, that force which com- 
preffes and confines this Air in the Apples* 
muft be equal to the weight of 48 of our 
atmofpheres, when the Mercury in the 
Barometer ftands at fair, that is 30 inches 
high.
