Analyjis of the Air. 1 07 



were at this feafon many hot days, with much 

 thunder and lightning, which deftroys the Air's 

 tlafticity 5 fo there were generated in all 489 

 cubick inches, of which 48 were reforbed. 

 The liquor was at laft very vapid. 



From the great quantity of Air generated 

 from Apples, in the following Experiment, 'tis 

 probable, that much more Air would have 

 rifen from the laxer texture of ripe undried 

 Grapes, than did from thefe Raifins. 



We fee from thefe Experiments on Raifins 

 and Ale, that in warm weather Wine and Ale 

 do not turn vapid by imbibing Air, but by fer- 

 menting and generating too much, whereby 

 they are deprived of their enlivening principle, 

 the Air 5 for which reafon thefe liquors are 

 beft preferved in cool cellars, whereby this 

 active invigorating principle is kept within due 

 bounds, which when they exceed, Wines are 

 upon the fret and in danger of being fpoiled. 



Experiment LXXXVII. 



Twenty-fix cubick inches of Apples being 

 mafbed Angnjl io, they did in thirteen days 

 generate 968 cubick inches of Air, a quantity 

 equal to 48 times their bulk ; after which they 

 did ia three or four days reforb a quantity equal 



to
