20 6 Anatyfis of the Air. 
rouzed into an elaftick ftate, is evident by 
thefe following Experiments, viz. 
Experiment LXXXV, 
March the 2d I poured into the bolt- 
head b , (Fig. 34-) forty two cubick inches 
of Ale from the Tun, which had been there 
fet to ferment 34 hours before: From that 
time to the 9th of June it generated 639 
cubick inches of air, with a very unequal 
progreffion, more or lefs as the weather 
was warm, cool, or cold, and fometimes 
upon a change from warm to cool, it rc- 
forbed air, in all 3 2 cubick inches. 
Experiment LXXXVI. 
March the 2d, 12 cubick inches of Ma- 
laga Raifins , with 18 cubick inches of wa- 
ter, generated by the 1 6th of April 41 1 cu- 
bick inches of air ; and then in 2 or 3 cold 
days it reforbed 35 cubick inches. From 
the 2 1 ft of April to the 16 th of May it 
generated 78 cubick inches; after which to 
the 9th of June it continued in a reforbing 
ftate, fo as to reforb 13 cubick inches 5 
there were at this fcafon many hot days, 
with much Thunder and Lightning, which 
deftroys the air’s elafticity ; fo there was ge-
