    It has been noticed by Hansen,* also by Tavel, that echinococcus cysts are principally found on the sides of the limbs where the principal blood-vessels course. In the neck they affect especially the neighbour- hood of the carotid artery. In many cases the first appearance of the tumour was connected by the patients with some injury received. This occurred in so many instances that it could hardly be attributed to merely accidental coincidence. .There can be no doubt that in some of these instances a vigorous muscular movement or an injury had displaced the cyst, so as to render it evident; in others, inflamation was inducedf and this speedily rendered the previously latent parasite obtrusive. The diagnosis of echinococcus cysts of the muscles is usually very difficult, unless the cyst be punctured or incised ; indeed, in the great majority of cases the real nature of the tumour has been discovered only at the time of operation. They may be mistaken for other kinds of cysts, for abscess, for lipoma, for sarcoma, or cancer. The treatment should be free incision of the sac, evacuation of its contents, free drainage, and antiseptic dressings. C. Hydatid Disease of the Female Breast. Bibliography. Haussmann.—Die Parasiten der Brustdruse. Berlin, 1874 (Birkett). Frequency.—The female breast is not a common seat of this parasite, for it is attacked in less than one per cent, of all cases. From various sources, Haussmann has collected 16 cases. Exclusive of these, there are instances recorded by several writers. Cases.—(1) Female, aged 27. Cystic tumour in right breast of nearly four years’ known duration, now of the size of a hen’s egg. The tumour was punctured, but no fluid escaped ; eight or ten days later it was incised and found to be a degenerated hydatid. Cure.f * Deutsche Zeitsclirift fiir Chirurgie. t Macgillivray : Aust.
