which will happen sooner or later, in Proportion to the increased

Magnitude of the Particles, and the smallness of the Vessels.

_Demonstration._

[Illustration]

C, D, E, F, G, H; Let the Dotts represent the increased _Moleculæ_ of

the Blood, it is evident that these must be stopt some where or other in

the Ramifications of the Vessels C, D, E, F, G, H, whenever the

Diameters of the _Moleculæ_ exceed those of the containing Vessels.
