Experiment XXVIII. 



Auguji 13. I Gripped the leaves off an 

 Apple-tree branch, and then fixed the great 

 end of the ftem in the gage ; it raifed the 

 mercury 2 -j*| inches, but it foon fubfided, 

 for want of the plentiful perfpiration of 

 the leaves, fo that the air came in almoft as 

 faft as the branch imbibed water. 



Experiment XXIX. 



I tried alfo with what force branches 

 would imbibe at their fmall ends, as they 

 are in their natural ftate, growing to the 



trees. 



Jugujl 2d, I cemented faft the gage r i z 

 (Fig. 14.) to the pliant branch b, of a dwarf 

 Gotten Pippin-tree, the fame from which I 

 cut the branch in Experiment 26 : As the 

 tranfverfe cut if imbibed the water, the mer- 

 cury rofe 5 inches obliquely in the tube z, 

 and 4 inches perpendicular. 



In this, as alfo in many of the precede- 

 ing Experiments, there were feveral wounds 

 in°that part of the branch which was with- 

 in the large tube r i ; which were made by 

 cutting off little lateral twigs, and fwelhng 

 eves "bat the branch might eafily enter the 

 ™ ' tube :
