Vegetable Staticks. 47 



I have tried the fame experiment with 

 feveral vine branches cut off, and fet in water 

 thus, but no water rofe into/! 



Thefe three laft experiments all mew, that 

 tho' the capillary fap-veffels imbibe moifture 

 plentifully; yet they have little power to 

 protrude it farther, without the afliftance of 

 the perfpiring leaves, which do greatly pro- 

 mote its progrefs. 



Experiment XVI. 



In order to try whether any fap rofe in 

 the winter, I took in January feveral par- 

 cels of Filberd-fuckers, Vine-branches, green 

 Jefiamine-branches, Philarea and Laurel- 

 branches, with their leaves on them ; and dip- 

 ped their tranfverfe cuts in melted cement, to 

 prevent any moifture's evaporating thro* the 

 wounds ; I tied them in feparate bundles, and 

 weighed them. 



The Filberd-fuckers decreafed in 8 days, 

 (fome part of which were very wet, but the 

 laft 3 or 4 days drying winds) the nth part 

 of their whole weight.
