Analyjis of the Ah. 181 



Experiment LXV. 



From 373 grains, or a cubick inch of 

 the coarfeft Sugar, which is the eflential 

 fait of the fugar-cane, there arofe 126 cu- 

 bick inches of air, equal to 36 grains, a lit- 

 tle more than ~ part of the whole. 



Experiment LX VI. 



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 Brijlol 

 hot well water, and of Holt water. In 

 Piermont 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 cif- 

 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 

 of the bottles. See Vol. II. p. 269, 272.
