fo that at noon day I could not fee it fo 
much as ftationary. 
Yet by Experiment the 3d, on the Vine 
in the garden pot, it is plain, that a very 
confiderable quantity of fap was daily pref- 
ling thro’ this ftem, to fupply the perfpira- 
tion of the leaves, before I cut the Vine off. 
And if this great quantity were carried up by 
pulfion or trufion, it mud needs have rifen 
out of the ftem into the tube. 
Now fince this flow of fap ceafes at once, 
as foon as the Vine was cut off the ftem, 
the principal caufe of its rife nmft at the 
fame time be taken away, viz. the great 
perfpiration of the leaves. 
For tho’ it is plain by many Experiments^ 
that the fap enters the fap veflels of plants 
with much vigour, and is probably carried 
up to great heights in thofe veflels, by the 
vigorous undulations of the fun’s warmth, 
which may reciprocally caufe vibrations in 
the veficles and fap veflels, and thereby make 
them dilate and contraft a little ; yet it feems 
as plain (from many Experiments, as parti- 
cularly Exper. 13, 14, 15. and Exper. 43.) 
where tho’ we are afiured that a great quan- 
tity of water pafied by the notch cut 2 or 3 
feet above the end of the ftem 5 yet was the
