Analyfis of the Air. \y\ 



come to full maturity, was generated 270 

 cubick inches of Air, the weight of which 

 Air was 77 grains, TO. i of the weight 

 of the Wheat, 



Experiment L VII. 



From a cubick inch, or 318 grains of 

 «Pft?/£,-was generated 196 cubick inches of 

 Air or 1 1 3 grains, i. e. fomething more than 

 J of the weight of the Teafe. 



Nine days after this Air was made, 1 

 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 ina- 

 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- 

 rit 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- 

 wards*
