That the Force was not only in the Root, but in the 
Stem and Branches, appear’d by feveral Experiments, 
pne of which was, that a Vine, at 44 Feet, 4 Inches 
in diftance from the Root, pulh’d up Sap with the 
Force of a Column of 30 Feet, 1 1 Inches of Water. 
By a nice Experiment he (hews, that the Sap does 
not come indifferently thro‘ all the Intenlices of 
the Wood; but is conBrted to its proper Veflels.- 
The Fibres, or Capillary Tubes, out of the bleed- 
ing Seafon, cannot protrude the Sap beyond their O- 
rifices in the Section of the Stem ; but, affifted by the 
Perfpiration of the Leaves, the Sap will rife in that 
very Branch, which would imbibe Water, if it was 
cut off, and a Tube applied to it with Water, poured 
in j nay, it wou'd alfo imbibe Water at the fmall End.
