    It is believed that no lost joints are reproduced. The animal is hermaph- rodite. It is sometimes over twenty feet long. Its movements are felt bv the patients within them. It has protruded many feet from, and asraiil withdrawn into, the anus. It is most, frequent in adults ; but has been found in the fetus. It is not always found alone, as regards its own or other species. Its habitat is the small intestines ; it sometimes extends into the large, or into the stomach. The head of the tenia lata differs from that of the taenia solium (as seen throuirh a microscope;) its joints are shorter and broader and differently united ; the pores are not on the edges, but in the centre of the flat surface; and it is not so easily broken across as the teenia solium. Its average length is fifteen feet. In England, Holland and Germany, the teenia solium is common ; in Russia, Poland and Switzerland, the tarnia lata; in France, both. LECTURE LXXIV. Entozoa—Continued.—Hydatids, Acejihalocysts, animals like bags of water, containing a thin colorless liquid and having only one aperture, often occur in various parts of the body, especially in the liver. They usually occur unattached, and sometimes in vast numbers, within a large cyst or cavity, and may destroy life by their bulk and pressure, according to the part occupied. Their presence can seldom be. divined; or if so, they can seldom be cured. A galvanic curreut or electric shock, passed through the part affected, or poisonous drugs, as mercury or iodine, are impotent to cure. They sometimes work their way to the surface, and escape through an ulcerated outlet. Cyslicerci are single cyst-like bodies with 6hort retractile necks. The cysticercus cellulosus inhabits, but rarely, the interfascicular areolar tissue of the muscles, and the eye. Trichina spiralis is a microscopic worm, and, sometimes in mvriads, infests the voluntary muscles. It gives rise to no symptoms, and is not, connected with any age, sex, or particular form of disease. Filaria Medinensis—Dracunculus, or Guinea-worm.—Symptoms.— This is a long, slender, round, uniform animal, like a fiddle-string, from five inches to twelve feet long, occurring in the subcutaneous areolar tissue of almost every part, but especially of the lower limbs. It is some- times solitary; it is epidemic sometimes in intertropical regions. Some- times there are no symptoms for a long while ; at length occur itching of the part, a sensation of something creeping under the skin, sometimes a cord-like ridge in the track of the worm ; finally a vesicle, or pustule, or little boil forms, from which, when broken, the animal's head protrudes ; there is fever, often ; sometimes much local suffering; sloughing of the areolar tissue ; and sometimes dangerous hemorrhage. Treatment of the Guinea-Worm.—Extract the worm gradually and care- fully, by Winding the protruding part round a small stick, or roll of adhe- sive plaster, day by day ; protect the roll by a bandage. When the worm is broken, violent local infl Animation, abscesses and sinuses and high irritative fever are said to ensue—owinir likely to the presence of dead animal matter, or of young filaria!. When superficial, the natives of Guinea, &c, make an incision in the skin about the middle, and pull the worm throjgh from both ends; then the part soon heals. No other medication does good, except, perhaps, assafetida as a preventative. Oiling the uncovered parts of the body might be a preventative. Cleanli- ness also is considerable protection. The filariae peculiar to the eye, or to the bronchial glands, ore very rare.
