cies of the Arteries the Blood is more^blended 
and mixed, as is plain to be feen in the Lungs

1 6 . By comparing the Sum of the tranfverfe 
Seftion of chofe feveral mefentcric and con- 
verging Arteries together, we may obferve that 
the firfl: and fecond Order of the mefenteric 
Arteries are nearly equal, viz. 0.228 0.234. 
0227, yet equal Quantities of Water were 
found to pafs in one third of the time thro’ 
the cut mefenteric Arteries, that they did 
thro' the cut converging Arteries of the flit 
Guts, that is fince the Quantities which flow 
thro* equal Tubes are reciprocally as the times, 
the Qiiantities in thefe converging Arteries 
ought to have been as P81.38 to 342 cubic 
Inches, whereas there flowed but ,-;^th parr.

the brafs Pipe, which was fixed to the Aorta 
was but 0.057 4 of ^he Sum 
of the other Arteries, yet 1148.5? cubic Inches 
would have pafled that in 6,6 minutes, when 
the great Branches of the Aorta were cut off, 
that is, 1.17 rimes as much would in that 
time flow thro* it as thro* the mefenteric Ar- 
irncs, and 3.5 times as much, as did pafs 
thro'
