They are commonest in the muscles of the tongue, neck, and shoulders, in the intercostal and psoas muscles, and in those of the quarter. The viscera—viz., the liver, kidneys, heart, lungs, etc.—are less commonly in- fested, and in these organs the cysts degenerate very rapidly. In animals which have been infested for a long time, the cysts may even have undergone caseo- calcareous degeneration, the liquid being absorbed and the lesions presenting the ajDpearance of little oblong firm nodules. On cutting through masses of muscle the vesicles protrude from between the bundles. In young animals, infestation with cysticerci causes wasting and ill-health; subsequently the patients improve in ajipearance, later on fatten, and gain marketable condition. Of the carcases examined in Prussian slaughter-houses between 1876—8t2, one in every 305 was found infested; between 1885—1)3, one in every 537. Treatment. There is no curative treat- ment.
