propel vifcrd Fluids along their Canals, its 
Motion is therefore flow ; but the quickefl 
Motion being always in the Axis of the 
Veffels, from the repulfive Coilifion or Re- 
fiflance of the Sides ; and the moft fluid 
Parts of the Blood being fufceptible of the 
greatefl Motion,, thefe muff therefore be 
chiefly propelled ; while the vifcidcr Parts 
lefs fit for Motion, as they confift of groiler, 
lefs prepared, and more attractive, or ad- 
hefive Particles, give the greatefl Refiftance 
to the Action of the Solids and Veffels, and

ened, foak’d in Moiflure, and become over 
flippery, have not Force to fhake them oft^ 
and throw them into the middle of the
