their expanding bubbles rifing of a very 
vifible fize when the weight of the incum- 
bent air is taken off the liquor in a vacuum. 
And as there was found a greater quantity 
of air in the deer’s horn, than in blood- 
we may alfo obferve it to be in a much 
greater proportion in the more folid parts o£ 
vegetables, than in their fluid: For we find 
in Experiment 55. 57. and < 5 o, that near 
one third part of the fubftance of the Peafe* 
heart of Oak and Tobacco, were by the ac» 
tion of fire changed from an un-elaftick 
ftate, to an elaftick air : And fince a much 
greater proportion of air is found in the 
folid than the fluid parts of bodies 5 may we 
not with good reafon conclude, that it is very 
inftrumental, as a band of union in thofe 
bodies, “ Thofe particles (as Sir Ifaac 
Newton obferves) “ receding from one
