Blood, which rifing fix Inches in the Tube 
fixed to the jugular Vein is part of 
the Force of the arterial Blood, and mud

8. The Diameters of the cut Orifices of 
the Arteries thro' which the Water paded off, 
Were at a Medium, one with another, equal to 
twice the Diameter of a Hair, which Dr. Jti- 
Tin by an accurate Eftimation found to be 
-^th part of an Inch ; hence thefe Arteries 
which are Inch Diameter, as they branch 
off from the Mefenterics (pread themfelves 
alternately, on each fide of the Guts, whence 
meeting again, their inofculating Branches 
form Areola s like thofe that are on the Leaves 
of Trees : And from thefe thus converging 
Arteries and fap Vellels, there branch ofl'near- 
ly at right Angles, without converging any 
more, much fmaller Arteries, and from thefe 
others again, both at right Angles, and like 
the fpread Fingers of a Hand, in fucceifive 
Series's in their Progrefs towards the Veins. 
The Diameters of the firft Series's of 
thefe uncQnverging Branches, may in a Piece 
of Gut well injefted with Vermilion, be ob-
