“ But, when the Particles of the Globule of Blood 
ec are mixed with the nervous Fluid, they will both 
ct together inclofe the Globule of Air again, and com-

This Syftem, however ingenious, as it admits of 
fo many bare Suppofitions, upon which thefe Au- 
thors found their Arguments, it will be difficult to 
think it the true Explanation of mufcular Motion : 
But admitting every Suppofition to be true, yet the 
Time that this kind of Nifus, Attractions Rare- 
faction , Fermentations &c. muft necdfarily take up 
in the Performance, can no way be accountable for 
the quick Motions performed by the Mufcles of the 
Organs 
* The only Difference that feems to be between this and the fore- 
going Author is, that the Aura , after being let loofe, and fwelling 
the Mufcle, flies off into the open Air, according to Bermuillis and 
the Mufcle ceafes to fwellt Whereas our prelent Author fays, his 
Globule of Air is again condenfed into as fmall a Space as before, 
and the Swelling and Contradtion of the Mufcle ceafes : However, 
their- Conclufion is the fame for the Continuance of the Motion or 
Swelling ; this Author requiring frefh Blood and Spirits fucceeding 
one another ; and the foregoing Author the fame, in thefe Words : — 
JWufculus iterum detumefcat , niji jugiter nova infiillentur Guttula 
Sued jiervofi, qua novam <& 7iovam pariendo Ebullitionem , Mufculurn 
in continua Ivfatione confer vent.
