lit Vegetable Static is. 
notch very dry, becaufe the attraction of the 
perfpiring leaves was much greater than the 
force of trufion from the column of water. 
From thefe Experiments, I fay, it feems 
evident, that the capillary fap veffels, out of 
the bleeding feafon, have little power to pro- 
trude fap in any plenty beyond their ori- 
fices ; but as any fap is evaporated off, they 
can by their ftrong attraction (affifted by 
the genial warmth of the fun) fupply the 
great quantities of fap drawn off by perfpi- 
ration. 
Experiment, XXXVI. 
April 6th at 9. a. m. rain the evening be- 
fore, I cut off a Vine on a fouthern afpeCt, 
at a (Fig. 18.) two feet nine inches from 
the ground, the remaining Item a b, had 
no lateral branches, it was 4 inch diameter 5 
I fixed on it the mercurial gage ay. At 1 1 
a. m. the mercury was rifen to z, 15 inches 
higher than in the leg x, being pulhed down 
at x, by the force of the fap which came 
out of the item at a. 
At 4 p. m. it was funk an inch in the leg zy. 
April 7th at 8 a. m. rifen very little, a 
fog: at 11 a. m. 'tis 17 inches high, and the 
fog gone.
