3 penne the whole body. ©The original-of their difpenfation, or place from 
whence they rife, is the liver, where blood is made; and that the firft fanguification 
-ismade there, and notin the heart, is apparent, becaufe there are no paffages to con- 
vey the chylus to the heart, nor any receptacles for the'excrements of the firlt con- 
-coction placed by the heart; all which requifites are’found in the liver. More- 
ever blood is, carried, from the liver to the heart, but not from the heart to the 
liver: for it cannot go.out of thesheart into the liver, becaufe of the valves, though 
mediately, when.it runs back out of the arteries, it may be carried thither. Alfothe 
ena cava sand portaenter not into the heart, but'the liver; atid, in a child in the 
womb, the navel-vein with ‘blood (whith nourifhes the child) goes not into the heart, 
_ but into the liver; nor is fanguification ever hurt but when the liver is hurt. The 
veins have only one tunicle, with many valves’ within, efpecially in the external 
jowts; they are nourifhed with blood, not with that contained within themfelves, 
but with that from the litele arteries ; for their connection is fuch with the arteries, 
that every vein is for the moft part attended with an artery/over which it lies, and 
which it touches, Galen faith, a vein is feldom found without atteries: but no ar- 
-tefyis-ever found without a vein. - Their form is:that of a conduit pipe ; ; their mag-
