series C No2, fig a & fig. b. -
<s>In both of the better illustrations, namely<\s> This is further illustrated in Series C
No2 and No3; and in both of these, two drawings are made, by which
the
distributions of the pulmonary arteries and veins
are brought into permanent contrast with one another,
by the colours, with which the arteries and veins
were respectively injected, being transposed; in
one, the arteries are red and the veins yellow, and
in the other the arteries are yellow and the veins red.
The minuter capillaries are more clearly shewn
by the yellow injection, and by adopting this plan
of transposition the characters of those directly
in communication with both the arteries and the veins
can be studied. It will be <s>arranged<\s> observed that the
capillaries from which the veins directly take their
origin and arranged in tufts, while those belonging
more strictly to the arteries are spread out in a
more even and uniform reticulation.
It will also be seen that there is in the upper sur=
=face of each lobule a rather more extensive ra=
=mification of the capillaries directly continuous
with the arteries and thus the capillaries of the veins
are arranged around the margins of each leaflet, and
speedily dip down into the sulci between the leaflets
to form larger veins in the interlobular spaces - This
is well shewn in series C No4 fig a.
