cording to Dr. Harvey and Lowers dou- 
ble that Quantity of Blood be thrown out at 
each Syflohy then the Number of extream ca- 
pillary Arteries will alfo be double that Num- 
ber, viz. 5>88i 6^. And if the Velocity in 
the Lungs be 27. 9 times greater as was found 
in Exper. IX. Nmnb. 6. then the Number of 
extream capillary Arteries there will be 
3541715- 
16. And how vaftly more numerous arc 
the many Branchings, Windings and Turn- 
ings of the Arteries and Veins, how innume- 
rable the lymphatic Veffels,' and fecretory 
Duds ? and thefe all adjuflcd and ranged, in 
the moft exa£l Symetry and Order, to (erve

Experiment XL 
I. A S to the Force with which the Blood 
is impelled from the right Ventricle 
of the Heart into the pulmonary Artery, it 
feems impradicable to attempt the finding of 
it, by fixing a Tube to that Artery, in the 
fame manner as to the carotid and crural Ar- 
teries
