Experiment X. 
I. \T/E in the foregoing Experiment 
W how very much the Velocity of the 
Blood is retarded, in its Paflage from the great- 
er, to the lefler Arteries in the Guts, notwith- 
ftanding the Sum of the Diameters and Areas of 
the leffer do confiderably exceed thofe of the 
greater. So that the Blood in pafling thro' the 
Mufcular, the Membranous, and other parts 
of the Animal, mull be carried on with innu- 
merable different Degrees of Velocity, and 
confequcntly in different Quantities thro* difl 
fimilar parts : But in the Lungs efpecially this 
Difference is remarkably great, for lince the 
whole Blood of the Animal inceffantly paffes 
thro* them ; by comparing the Proportion, 
which the Quantity of the Lungs bears to 
the reft of the Body, w^e may make fome ef^
