 Duke-cberry-branch five feet high, and one 

 inch diameter, but did not cut away any of 

 the bark or wood at the great end j I filled the 

 tube with water, and then cut a flice off the 

 bark an inch long, 3 inches above the great 

 end ; it bled at the lower part mofl freely, 

 while the upper part continued dry. 



The fame day I tried the fame experi- 

 ment on an Apple- branch, and it had the fame 

 effecl. 



From thefe experiments 'tis probable, that 

 the lap afcends between the bark and wood, 

 as well as by other parts. 



And fince by other experiments it is 

 found that the greateft part of the fap is 

 raifed by the warmth of the fun on the 

 leaves, which feem to be made broad and 

 thin for that purpofe ; for the fame reafon, 

 it's mofl: probable, it fhould rife alfo in thofe 

 parts which are mofl expofed to the fun, as 

 the bark is.
