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

diluted muriatic acid, but which leave a residue of animal matter after all the carbonate has been dissolved. These bodies begin to be formed as soon as the neck ap pears & continue to increase in number as it increases in size. The probable office of bodies so purely mechanical, both in their form & com position is most likely one which is purely mechanical also. Perhaps by giving a degree of solidity to the neck they enable the circular, & longitudinal fibres entering into its composition, to effect its protrusion from the ventral ca vity, & thus serve as an example of a very low type of an internal skeleton. The terminal surface of the neck is of a quadrangular form, each angle being occupied by a circu lar disc or sucker, & its centre contains an apparatus of hooklets, (see Plate 1. fig: 2) & thus the four suckers & hook lets are all situated nearly upon the same planes, a position which would be advantageous for the employment of these organs when these animals are transferred from their deeply-seated & confined position between the muscular fibres to the free surface of the mucous membranes. The suckers are of a circular figure with a diameter of about 1/750 of an inch. See Plate 1. fig: 4. Each consists of two or three membranous folds placed at different depths from the surface
