Six to ten feet long, with seven to eight hundred joints, and a circlet of hooks (Fig. 136), lives in the human intestine. Several of its sexually mature joints are commonly pinched off at a time, and if these are picked up from a field or dung-heap by a pig, the contained eggs develop into " pork measles" (Gysticercus, Fig. 140), which are especially abundant in.

Young pigs not more than six months old are most in danger of becoming measly. A tolerably large number of measles can be borne very well, but if very.
