 was raifed up the tube d z as high as z, viz, 



8 inches. 



The next morning at 8 o' clock, the mer- 

 cury was fallen to 2 inches height, and 2

 branch with leaves imbibed much more than 

 a column of 7 feet height of water could in 

 the feme time drive through 13 inches length 

 of the biggeft part of its ftem. And in the 

 following experiments we mail find a farther 

 proof of their ftrong imbibing power. 



May 25, I cut off a branch of a young
