Ground, receiving its Nouriihment only from two 
other Trees, to which it was inarch’d, and from which 
it was fufpended 5 as alfo by a Bough with two 
Branches cut off from a Tree, one Branch of which 
out of the Water preferv'd its Verdure, and receiv’d its 
Nourifliment from the other Branch immers’d in Water, 
whilfl another Bough of the fame fort without that > 
help, immediately wither’d. 
That there is a lateral Motion of the Sap thro* 
Veflels, whereby the longitudinal Capillary Fibres 
communicate with one another, he prov’d chiefly by 
the following Experiment, viz. He cut four long 
Notches, one above another, (but looking towards the 
feveral Cardinal Points) in a pretty large Branch, whofe 
Section fome Inches below the faid Notches, was im- 
mers’d in Water ,* and found, that by the Attraction of 
the Fibres and Perfpiration of the Leaves, the Moifture 
rofe plentifully, notwithflanding that the Continuity of 
the greatefl: part (if not of all) the longitudinal Fibres 
was deftroy’d by tho^e deep Notches. 
This lateral Motion may alfo be deduc’d, from ob- 
ferving, that Branches will grow out of Roots, and 
thrive very well ,• and that Elders, Sallows, Willows, 
Briars and Vines will grow, by putting either End of 
a Stem or Branch into the Ground. 
He obferves, that there is indeed, an alternate Rece- 
ding and progreflTive Motion of the Sap, w’hich recedes 
w hen cold Weather and Rain fucceeds hot Sunfhine, 
the Trees then imbibing the Rains and Dews which 
fall upon the Leaves; but upon the return of the hot 
Weather, the Perfpiration is renew’d, and the Sap rifes 
again. This is fufflcient to account for Jeflamine and, 
the PafTion-Tree receiving a gilded TinCfure below^the 
gilded inoculated Bud; which has been given as an 
Inflance of the Circulation of the Sap : But i\\t Ilex
