On the Structure and Development of the Cysticercus cellulosae, as Found in the Pig, by George Rainey

is an accurate representation of one of these animals folded up in its cyst. This measures as it is thus folded up 1/16 of an inch in length. Plate 4, Fig: 1. shews a Cysticercus re= moved from its adventitious cyst. It has still somewhat of the folded character of the preceding specimen. This is 1/7 of an inch in length, & 1/28 in breadth. The interior of a cyst being smaller than the animal= cule contained therein, it naturally follows, that during its growth, one portion must be folded over another. By this means it is adapted to the confined locality, in which it is lodged during the period of its development. Hence the ventral portions of all Cysticerci are, when first taken from their cysts very much plicated, but these plicae disappear, the ventral sac becoming distended soon after a Cysticercus is placed in contact with fluid. Up to this point of the develop- ment of the Cysticercus it is a simple cyst growing by the assimilation of fluid imbibed equally by every part of its surface, no one part dif= fering sensibly in its structure from another. No portion of this surface pre= sents any indication of incipient hooklets or suckers. There is nothing either on its surface, or in its interior analogous to the structure of an ovum
