 cubick inch, or 135 grains of heart of Oak, 

 frelh cut from the growing tree, were 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 thirty grains, 

 -"- part of* the weight of 135 grains of Oak. 

 I took a like quantity of thin (havings from 

 the fame piece of Oak, and dried them gently 

 at fome diftance from a fire for twenty-four

 grains for the folid part of the Oak : Then 

 the 30 grains of Air will be i. 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 inftantly.
