a Man's Body,, in the following manner, viz, 
Suppofing as is mentioned in Exper, VIII. 
Numb, 8. that the Area of the tranfverfe Sec- 
tion of the Aorta in Man, is 0.4187 Inch^ 
and that the Length of the Cylinder of Blood, 
which is thrown out at each Syjlole of the 
left Ventricle, is ^,^6 Inches; and the Area 
of a tranfverfe Seftion of a fine extream capil- 
lary Artery being there fet at 0.000025)8 Inch : 
Then fince equal Cylinders are as their Bafes 
and Heights, the fine capillary Cylinder, e- 
qual to the Cylinder thrown out in each SyJ- 
tole of the Heart, will be 55639.518 Inches 
long : This Number multiplied by ten gives 
the Sum of that Column in A Inches, viz. 
55639.98 each of which was the Space the 
Blood flowed in nine Seconds. But this Length 
being to pafs the extream capillary Arteries of 
a Man, in 7^th part of a Minute, that is in 
^ of nine Seconds, (the Time in which the 
0*0 9 
Blood moved i\th Inch in the Frogj tho» 
not with greater Velocity than in the Frog; 
therefore the Number of thofe extream Arte- 
ries in Man, muft be proportionably increafed 
by multiplying 556399.8 by 8.88. the Pro. 
du£t is 494083, the aflonifliing Number 
of extream capillary Arteries. And if ac-
