10. Bat if with Dr. Harvey zxiA Dr. Low^ 
er we fuppofe two Ounces of Blood, that is 
5.318 cubic Inches to be thrown out at each 
Syjlole of the Ventricle, then the Velocity of 
the Blood in entering the Orifice of the Aorta 
will be double the former, viz- at the rate of 
145).! Feet in a Minute, and a Quantity of 
Blood equal to the Weight of a Man's Body 
will pafs in half the Time, viz- iS.ij Mi- 
nutes. 
11. If we fuppofe, what is probable, that 
the Blood would rife 7+t Feet high in a Tube 
fixed CO the carotide Artery of a Man, and that 
the inward Area of the left Ventricle of his 
Heart, is equal to fifteen (quarc Inches, thefc 
multiplied into 7 -ft Feet give 1550 cubic 
Inches of Blood which prefles on that Ventre 
cle, when firft it begins to contraft, a Weight 
equal to 51.J Pounds. 
1 2. That we may the more readily compare 
the abovementioned fevcral Eftimates toge- 
ther, I fliall here rangq^them in order in a 
Table.
