riments and Obfervations, and comparing them im- 
partially, they have fupplied the red: by Conjed-ures, 
and endeavour’d to fupport their H^potliefis by other 
new Suppofitions. It is upon this account that they 
have fuppofed particular Vefiels (like Arteries^ to car- 
ry up the Sap from the Roots to the Extremities or 
Leaves, and others dike Veins) to bring the 
Sap back again to the Roots; imagming the iormer to 
be chiefly in the middle of the Wood, and the latter to 
come down between the Bark and the Wood : But 
they did not cenflder, that a Plant is very cifiierently 
tiourifhed from an Animal, and therefore requires a 
very different Mechanifm and Strudure for its Growth 
and Support. 
Our Author has difproved the above-mentioned O- 
pinion', by feveral Experiments and Obfervations ; the 
chief of which are the following. 
1. Having cut a long Notch in a growing Branch, 
which had Leaves on, he obferved, that the Notch 
was moift at the Bottom towards the Root, and not 
at the Top. 
2. He made the fame Experiment with another 
Branch fet in Water, which imbib’d the Liquor at a 
tranfverfe Sedion below the Notch, and found the 
Notch as before. 
3. He obferv’d, that in the Spring the Sap rifes 
plentifully between the Bark and the Wood, and that 
chieriy in Vines; and that if a Ringlet of Bark be ta- 
ken off all round in bleeding Trees, the Bleeding a- 
bates moffly in the upper part of the bare place. 
4. The Sap will move any way by the Attradion 
of the fame Capillary 1 ubes, and Ferfpiration ot the 
Leaves ; lliewn by an Apple Tree-Branch, w'hich drew 
up Moiflure plentifully at the fmall End; by a Tree, 
which throve, tho’ its Root was taken out of the 
Ground,
