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.
