In the case of large or multiple hepatic cancers, the trunk of the hepatic artery is also considerably enlarged. To form an idea of the relation of the vessels, one ought to compare the appearances presented by them in injected preparations. In Plate VIII., Fig. 2, the portal vein is injected red, and the hepatic artery yellow. In Plate VIII., Fig. 1, the portal vein is yellow, and the hepatic artery blue. In Plate VII., Figs. 3 and 4, the portal vein is yellow, the hepatic vein red, and the hepatic artery blue. t The statements of different observers respecting the vascular apparatus of cancer are very various. Whilst Cruveilhier referred the seat of hepatic cancer to the venous capillaries, and Thomas Meyer (Carcmome der Leber, Basel. 1843, s. 20) regarded the portal vein as the starting-point of the morbid growth, Schroeder van der Kolk (Observatione$ AnatomicoPathologica, 1826, Fasc. I., p. 46) and Berard (Cruveilhier, Anal. Pathol, Livr. XII., p. 6), relying upon the results of injection, have denied entirely the participation of the veins. I have examined a large number of hepatic cancers, which were injected from all three vascular trunks, and have found none but large branches of the portal vein close to, or passing through, the tumour, but no capillary ramifications of this vessel; the morbid growth has always been supplied with its vessels by the hepatic artery, which has been the only vessel injected as far as its capillaries. vessels are usually thin, like those of capillaries, notwithstanding their size, and hence they are easily torn, and give rise to haemorrhages, which, in most cases, are limited to the cancerous mass, but occasionally escape into the peritoneum, in conseq...
