Analyfis of the Air. 177 
come to full maturity, was generated 270 
cubick inches of air, the weight of which 
air was 7 7 grains, viz. ~ of the weight 
of the Wheat* 
Experiment LVII. 
From a cubick inch, or 318 grains of 
*Peafe, was generated 396 cubick inches of 
air, or 11 3 grains, i. e. fomething more 
than jr 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 flaflied : Then I immediately im~ 
merfed the mouth of the receiver in the wa- 
ter, to extinguifh the flame. This I repeated 
S or 10 times, and it as often flaflied, after 
which it ceafed, all the fulphureous fpirit be- 
ing burnt. It was the fame with air of di- 
| ftilled Oyfter-fticil and Amber, and with new 
j diftilled air of Peafe and Bees-wax. I found 
| it the fame alfo with another like quantity 
of air of Peafe 5 notwithftanding 1 waflied 
1 that air no lefs than eleven times, by pour- 
1 ing it fo often under water, upwards, out 
of the containing vefiel, into another in- 
; verted receiver full of water,
