Extract

The Acephalocyst, or simple Hydatid, is composed of a vesicle, containing a watery fluid, which, in the normal state of the creature, is quite transparent and colourless (Pl. XIV., fig. 1.) The internal surface of the vesicle is generally studded with numerous cells of various sizes, many of which are found detached and floating loose in the fluid contained in the vesicle. These are the young Hydatids. Their development will be described when we come to that portion of the present paper, which has been set apart for that purpose.
