tho* a Limb be cut off, and the Space in it imme- 
diately wanting, and although the fame Quantity of 
Blood, fupply’d by Digeftion every Day, is carried 
into the Veflels, yet their Diftenfibility is fuch, that 
the only Change they can fuffer is further Repletion. 
And as to the Mufcle itfelf, if, during a violent 
Adion, there fhould happen any Danger of Injury, 
it would be perceived immediately by the Mind, and 
remedied by ceafing her Impulfe on the Nerve and 
Cells , and thereby granting a free Circulation in- 
ftantly.

As to the ^Equilibration between two antagonize 
Mufcles, Dr. Stuart , in his Ledures *, thinks, that 
As each Antagonift has its diftind Nerve or Nerves 
“ without Communication, and the antagonift Muf- 
iC cles communicate one with another by one com- 
“ mon Trunk of an Artery, and one common Trunk 
“ of a Vein; they are like two antagonift Scales in 
44 Equilibria , over which the Mind has a diftind 
4£ Power, by diftind Nerves, for determining the 
“ animal Spirits, and thereby the Blood, to either 
4t Side at Pleafure, without affeding the other : And 
££ concludes from thence •f*, that if what is taken 
from one be added to the other, the Momentum 
“ of the Motion will be doubled.”
