The lesions are I'epresented by cysts aloneâ,hj semi-transparent bladders, each of ^yhich contains a scolex or head armed ^Yith four suckers and a double crown of hooks. The little bladders are most commonly found in the muscles, lodged in the interfascicular tissue, which they slightly irritate. The number present varies extremely, depending on the intensity of infestation and the number of eggs swallowed. Whilst in some cases difficult to discover, in others they are so numerous that the tissues appear stre\\n with them. 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 visceraâviz., the liver, kidneys, heart, lungs, etc.âare less commonly in- fested, and in these organs the cysts degenerate very rapidly. In animals which have Ijeen infested for a long time, the cysts may even have undergone caseo- calcareous degeneration, the liquid Ijeing absorbed and the lesions presenting the appearance 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; suljsequently the patients improve in api)earance, later on fatten, and gain marketable condition. Of the carcases examined in Prussian slaughter-houses between 1870â8'2, one in every 305 was found infested; between 1885â93, one in every 537. ^^''- 3^-âHalf of hog, showingthe mi i rm ⢠, ⢠, , portions mo
