of the Pulmonary veins
Having now traced the blood brought
by the Pulmonary artery and having
seen that every portion of it reaches the leaflets,
and is there distributed in such a manner as
to be <s>exposed<\s> suited to its fullest exposure to
the atmosphere, but not in any degree so as to
furnish any structure with its supplies for its repairs or construction, it remains to be
seen in what way this blood, now become arte=

are to conduct it back to the heart -
The arrangement by which this is done, would
be altogether as simple and unequivocal as
the distribution of the artery, were it not that
a diverticulum of a part of the blood returning
from the leaflets is made, whereby a portion of it
