Experiment XLII. 



July 27th, I repeated Monfieur Perault's 

 Experiment ; viz, I took Duke-cherry, slp- 

 ple and Curran- boughs, with two branches 

 each, one of which a c (Fig. 25.) I immer- 

 fed in the large vefTel of water e d } the 

 other branch hanging in the open air: I 

 hung on a rail, at the fame time, other 

 branches of the fame forts, which were then 

 cut off. After three days, thofe on the rails 

 were very much withered and dead, but the 

 branches b were very green -, in eight days 

 the branch b of the Duke-cherry was much 

 withered : but the Cur ram and Apple-branch 

 b did not fade till the eleventh day: Whence 

 'tis plain, by the quantities that mufti be per- 

 fpired in eleven days, to keep the leaves b 

 green fo long, and by the wafte of the water 

 out of the veflel, that thefe boughs b mull 

 have drawn much water from and through 

 the other boughs and leaves c y which were 

 immerfed in the vefTel of water. 



I repeated the like experiment on the 

 branches of Vines and Apple-trees, by run- 

 ning their boughs, as they grew, into large 

 glafs chymical retorts full of water, where
