Diseases of metabolism and of Diseases of metabolism and of the blood, animal parasites, toxicology diseasesofmetabo00cabo Year: 1906 ECHINOCOCCUS DISEASE 527 they breed in the capillaries of the portal circulation explains the frequent implication of the liver. Often the embryos lodge permanently in the mesen- teric glands. Others, by means of the lymph-vessels, or by various avenues of communication, invade the peritoneal and pleural cavities: others enter the thoracic duct, thence find their way into the jugular vein and to the right heart, and are retained in the lung or are distributed to near or even distant organs. After the echinococcus embryo has reached its destination it develops very slowly; we would digress too far if we described the individual phases of its development. After the lapse of weeks or months, we again find the echinococcus in a round white cyst which gradually increases in size. Its walls are composed of a characteristically layered cuticula and a parenchymatous Layer. After a certain time the latter shows upon its inner surface the so-called breeding capsules, which hang upon a short pedicle from the parenchymatous layer, and are surrounded by a transparent fluid not containing albumin. Some of the breeding capsule- develop internally, some externally, producing echinococcus heads, the so-called scolices.
