As to 'vegetable Subftances, from half a 

 cubick inch, or 1 3 5 grains of heart of Oak> 

 freih cut from the growing tree, was gene- 

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

 tity equal to 216 times the bulk of th& 

 piece oiOah its weight was above 30 grains> 

 i part of the weight of 1 3 5 grains of Oak. 

 I took a like quantity of thin (havings from 

 the fame piece of Oak, and dryed them 

 gently at lbme diftance from a fire for 24 

 hours, in which time 44 grains weight of 

 moilture had evaporated j which being de- 

 duced from the 1 3 5 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.
