It is one of the great BIS SEMINATION 265 triumphs of pathological histology that it has demonstratedthat carcinoma takes its type of epithelium from the secretinggland in which it arises. This power of independent growth possessed by the epithe-lium of cancer is a very dangerous feature, and does notalways need blood- or lymph-vessels for its manifestation. It. X 130 Fig. 153.—Section through a portion of an inguinal lymph-gland infected withcancer: the primary disease was in the rectum. (After Foulerfon.) sometimes happens that an abdominal viscus is attacked bycancer, and a small outgrowth makes its way through theperitoneal covering and bursts, and sheds its cells into thegeneral peritoneal cavity; these are distributed by the peri-toneal fluid and the movements of the bowels, and in a fewweeks the whole of the serous membrane will be dotted withhundreds, and sometimes thousands, of nodules, each repro-ducing the type of the parent tumour. This mode of epithe-lial infection of the peritoneum I have found in cancer ofthe gall-bladder, ovary, and especially in cancer of the bodyof the uterus; no form of dissemination gives rise to such 266 EPITHELIAL TUMOURS innumerable secondary nodules as this, nor demonstrates ina more remarkable way the power of ep
