thrown out of the Ventricle into the Orifice 
of the Aorta may be thus computed, v'lZr 
the Capacity of this Ventricle being equal to 
ten cubic Inches, and the Area of the tranf. 
verfe Section of the Aorta being 1.03^, by 
whiclx. dividing the ten cubic Inches, the 
(Quotient is the Length of the Cylinder 
of Blood, which is formed in paffing thro’ 
the Aortds Orifice, at each Syjlole of the 
Ventricle. And a Horfe's Ventricle of his 
Heart conrrading or his Piilfe beating ^6 
times in a Minute, that is 2160 times in an 
Hour, then a Column of Blood fo many 
times 5^.(>4 Inches, or 208 15?. 4 Inches long 
or 1754.5? Feet will pafs in an Hour.

ing which that Quantity of Blood is propell’d, 
being eflimated to be done in one third of the 
Space of time between each Pulfe, the Ve- 
locity of the Blood during each Syjlole will 
be thrice as much, at the Rate of 5104.7 
Peer, i. e, 0.5)8 of a Mile in an Hour or %6.j 
Feet in a Minute. 
26, Now this Velocity is only the Velocity 
of the Blood at its firft entering into the 
Aorta, in the Time of the Syjlole-, in con- 
fequcnce of which the Blood in the Arteries,
