of air by diftillation, a good part of which 
was roufed by the adion of the fire from a 
fixed to an elaftick ftate.

tender fibrous roots, with the fmall end 
upwards at n , and the veflel// full of wa« 
ter ; then upon pumping large drops of wa- 
ter followed each other faft, and fell into 
the ciftern x > which had no water in it.
