weighed, fome hours after it was burnt, 
having run more per deliquium by abforbing 
the moifture of the Air, it had increafed a 
grain in weight. 
Experiment LV. 
As to vegetable Subfiances , from half a 
cubick inch, or 1 3 5 grains of heart of Oak , 
frefh cut from the growing tree, was gene- 
rated 108 cubick inches of Air, i. e. a quan- 
tity equal to 2 1 6 times the bulk of the piece 
of Oak, its weight was above 30 grains, 
q, part of the weight of 1 3 5 grains of Oak. 
I took a like quantity of thin (havings from 
the fame piece of Oak , and dried them 
gently at fome diftance from a fire for 24 
hours, in which time 44 grains weight of 
moifture had evaporated; which being de- 
duced from the 135 grains, there remains 
91 grains for the folid part of tb,z Oak: 
Then the 30 grains of Air, will be -f of 
the weight of the folid part of the Oak. 
Eleven days after this Air was made, I put 
a live Sparrow into it, which died inftantly.
