6 , But on weighing all the flefliy and other 
membranous Parts of another Dog, thro' 
which the arterial Blood paffes; that is, exclu- 
five of the Bones and Lungs, I found the 
whole Weight to be eighteen Pounds eleven 
Ounces, of which the flit Gut weighing one 
Pound two Ounces was therefore r^th part 
of the whole : So that Bulk for Bulk there 
paffed 30.27 times more Water thro* the Ar- 
teries of thefe flit Guts than thro* the reft of 
the Arteries of the Body, and that with a 
Force no greater than that of the Heart. 
7. Which may reafonably be attributed to 
thefe feveral Caiifes, as to the much greater 
Fluidity of Water than of vifeid Blood, to 
the more relaxed State of thefe Arteries in the 
dead than in the living Animal 5 for tho* the 
Arteries and Veins of a dead Animal being then 
freed from the diflending Force of the Blood 
do contratf, yet with equal Forces, thofe of 
the dead Animal will dilate more than thole 
of a live Animal : But this more plentiful 
Flow of Water is principally owing to the 
great DilFerence there is in Size, between theft 
cut capillary Arteries, and the fuccceding Se- 
ries's of exceeding fmall Ramifications, and that 
at right Angles^ thro* which the Blood pafles
