Surfaces.
In each and all of each of these different <s>structures the<\s> portions
of the lungs, the shape which they present consists
of three distinct surfaces, clearly defined by margins
more or lass acute. They exhibit, first an upper
and somewhat convex surface in which the capil=
=lary blood-vessels, principally in connection with
the pulmonary artery are seen; next an inner or
flat surface forming the interlobular surface and
which in the aggregate corresponds with that portion
of the lungs, which lies in contact with the peri=
=cardium; and thirdly the under surface, which
is rather concave than otherwise and is that portion
<s>of the lungs<\s> which lies upon the other leaflets or
lobules and coincides in the aggregate with that
portion of the lungs, which lies upon the diaphragm.
A transverse section of each <s>lung<\s> leaflet therefore is some=
=what triangular in form, and the space included
between the <s>leaflets<\s> surfaces of each leaflet is filled
up with a spongy tissue, and the name of aircells
is usually given to the interstices within it -
Each group of lobules, each lobule and each leaflet
may therefore as far as these particulars go be looked
upon as a diminutive but perfect lung -
The capillaries belonging to the two surfaces last men=
