Analyfts of the Air. 171 
come to full maturity, was generated 270 
cubick inches of Air, the weight of which 
Air was 77 grains, 'viz. i of the weight 
of the Wheat, 
Experiment LVII. 
From a cubick inch, or 3 1 8 grains of 
was generated S9<^ cubick inches of 
Air or 1 1 3 grains, /. e. fomething more than 
t of the weight of the Teafe. 
Nine days after this Air was made, I 
lifted the inverted mouth of the receiver 
which contained it, out of the water, and 
put a lighted candle under it, upon which 
it inftantly flafhed : Then 1 immediately im- 
merfed the mouth of the receiver in the wa- 
ter, to extinguifh the flame. This I repeated 
8 or 10 times, and it as often flafhed, af- 
ter which it ceafed, all the fulphureous fpi- 
I'it being burnt. It was the fame with Air 
of diftilled Oyfterfhell and Amber, and with 
new diftilled Air of Peafe and Bees- wax. I 
found it the fame alfo with another like 
quantity of Air of Peafe; notwithftanding I 
wafhed that Air no lefs than eleven times, 
by pouring it fo often under water, up-
