if any branch can raifc mercury i 2, inches, 
it will raife water 13 feet 8 inches : A fur- 
ther allowance being alfo madejfor the per- 
pendicular height of the water in the tubes, 
between r and z the top of the column of 
mercury 5 for that column of water is lifted 
up by the mercury, be it more or lefs. 
At the fame time, I tried a Golden Re- 
nat e branch 6 feet long, the mercury rofe 
but 4 inches, it rifing higher or lower in 
branches nearly of the fame lizc and of the 
fame kind of tree, according as the air if- 
fued thro 5 the item, more or lefs freely* 
In the preceding experiment on the Non- 
pareil branch, I had fucked a little with my 
mouth at the fmall end of the tube, to get 
fome air bubbles out of it, before I im- 
merfed it in the mercury 5 (but thefe air 
bubbles are belt got out by a fmall wire 
run to and fro in the tube) and this fac- 
tion made air bubbles arife out of the tranf- 
verfe cut of the branch 5 but tho' the quan- 
tity of thofe air bubbles thus fucked out, 
was but fmall 5 yet in this and many other 
experiments, I found that after fach fac- 
tion, the water was imbibed by the branch, 
much more greedily, and in much greater 
quantity than the bulk of the air was, which
