 hot weather ; after which they were ftatio- 

 nary, neither reforbing nor generating Air in 

 many days. 



A very coarfe Brown-fugar, with an equal 

 quantity of water, generated nine times its 

 bulk of Air 5 Rice-four fix times its bulk; 

 Scurvy-grafs leaves generated and abforbed 

 Air; Peas, Wheat and Barley did in Fer- 

 mentation alfo generate great quantities of 

 Air. 



That this Air, which arifes in fuch great 

 quantities from fermenting and dhToiving 

 vegetables, is true permanent Air, is certain, 

 by its continuing in the fame expanded elaftick 

 ftate for many weeks and months; which ex- 

 panding watry vapours will not do, but foon 

 condenfe when cool. And that this new gene- 

 rated Air is elaftical, is plain, not only by its 

 dilating and contracting with heat and cold, 

 as common Air does, but alfo by its being 

 compreffible, in proportion to the incumbent 

 weight, as appears by the two following Ex- 

 periments, which (hew what the great force 

 of thefe aerial particles is, at the inftant they 

 cfcape from the fermenting vegetables.
