ijo Analyjis of the Air\ 



Experiment LV. 



As to vegetable Suhftances, from half a 

 cubick inch, 01-135 grains of heart of Oak> 

 frefh cut from the growing tree, was gene- 

 rated 108 cubick inches of Air, i. e. a quan- 

 tity equal to 216 times the bulk of the 

 piece of Oak, its weight was above 30 grains? 

 4 part of the weight of 135 grains of Oak. 

 I took a like quantity of thin (havings from 

 the fame piece of Oak, and dryed them 

 gently at fome diflance from a fire for 24. 

 hours, in which time 44 grains weight of 

 moifture had evaporated 5 which being de- 

 duced from the 135 grains, there remains 91 

 grains for the folid part of the Oak : Then 

 the 30 grains of Air, will be f of the weight 

 of the folid part of the Oak. 



Eleven days after this Air was made, I 

 put a live Sparrow into it, which died in- 

 ftantly.
