Anahjfis of the Air. x 8 1 
Experiment LXV. 
From 373 grains, or a cubick inch of 
the coarfeft Sugar 3 which is the effential 
fait of the fugar-cane, there arofe 126 cu- 
bick inches of air, equal to 3 6 grains, a lit- 
tle more than tV part of the whole. 
Experiment LXVL 
I found very little air in 54 cubick inches 
of Brandy , but in a like quantity of Well- 
water I found one cubick inch. And it 
was the fame in a little quantity of Bristol 
hot well water, and of Holt water. In 
Tiermont water there is near twice as much 
air, as in Rain or common water , which air 
contributes to the brisknefs of that and 
many other mineral waters. I found thefe 
feveral quantities of air, in thefe waters* 
by inverting the nofes of bottles full of 
thefe feveral liquors, into fmall glafs ci£ 
terns full of the fame liquor. And then 
fetting them all together in a boiler, where 
having an equal heat, the air was thereby 
feparated, and afcended to the upper parts 
©f the bottles.
