come to full maturity, were generated 270 

 cubicle inches of air, the weight of which 

 air was yj grains, viz. ". of the weight 

 of the Wheat. 



Experiment LVII. 



From a cubick inch, or 318 grains of 

 Peas, were generated 396 cubick inches of 

 air, or 113 grains, /. e. fomething more 

 than ' of the weight of the Peas. 



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 I 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, after 

 which it ceafed, all the fulphureous fpirit be- 

 ing burnt. It was the fame with air of di- 

 ftilled Oyfler-ihell and Amber, and with new 

 diftilled air of Peas and Bees-wax. I found 

 it the fame alfo with another like quantity 

 of air of Peas; notwithflanding I wafhed 

 that air no lefs than eleven times, by pour- 

 ing it fo often under water, upwards, out 

 of the containing vefTel, into another in- 

 verted receiver full of water,
