    Chapter XXVI. THE CYSTICEECUS TELiE CELLULOSE. The Cysticercus telse cellulosse1 is the only species of the cysticerci which need be described here. Like the hydatids, it is commonly enclosed in a cyst formed of areolar tissue, which is more or less condensed, according to the nature of the organ in which it is developed; it is usually solitary. The cyst may undergo modification of structure, and may acquire greater consistence and thickness, in propor- tion to the length of time during which it has existed; the vesicular worm itself experiences various changes, the termination of which is that it is probably destroyed, whilst its empty and modified cyst remains. Laennec, having observed vesicles in the liver of a person in whom cysticerci were found in several organs of the body, considered that these vesicles were the cysts of former cysticerci; analo- gous facts which have been remarked in the instance of hydatids, and certain nematoid worms of which the cysts remain after the entozoa have been destroyed, and the striking alterations which have been demon- strated in cysticerci of old standing, conduce to render this view very probably a correct one. This species of cysticercus is most frequently met with in the intermuscular areolar tissue of the trunk, of the limbs, of the heart, and of the intestines, in 1 The name of this species of Cysticercus is derived from the circumstance of its being found in the areolar, or as it was formerly termed cellular, tissue. The word tela*, although grammatically necessary, is commonly omitted by writers.
