been more mercury in the gage 5 it being 
all forced into the leg y z>. From this time 
to May 5 th, the force gradually decreafed. 
The greatefl: height of the mercury being 
3 2 1 inches 5 the force of the fap was 
then equal to 36 feet s L inches height 
of water. 
Here the force of the riling fap in the 
morning is plainly owing to the energy of 
the root and Item. In another like mercurial 
gage, (fixed near the bottom of a Vine which 
run 20 feet high) the mercury was raifed by 
the force of the fap 38 inches equal to 43 
feet-)- 3 inches 4-7 height of water. 
Which force is near five times greater than 
the force of the blood in the great crural ar- 
tery of a Horfe ; feven times greater than 
the force of the blood in the like artery of 
a Dog 5 and eight times greater than the 
blood’s force in the fame artery of a fallow 
Doe : Which different forces I found by 
tying thofe feveral animals down alive upon 
their backs 5 and then laying open the great 
left crural artery, where it firft enters the 
thigh, I fixed to it (by means of two brafs 
pipes, which run one into the other (aglafs 
tube of above ten feet long, and Tth of an
