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

The Development of the Cysticercus cellulosae. The earliest indication of this species of Cysticercus, which admits of certain recognition as a form of cystic entozoon, is the presence of a selection of uniform corpuscles of about 1/2666th of an inch in length & 1/8000th in brea[d]th, mixed with very minute highly refractive molecules of different sizes in the substance of a primary fasciculus of a muscular fibre, or between its sarco lemma & the sarcous elements. See Plate 2, fig: 1. Though such a collection of corpuscles has a moderately definite shape m being somewhat fasiform, yet it has not a com- plete investment. It soon however acquires a very distinct membranous covering which is first apparent about its middle, & afterwards at its extremities. Its di= mensions in this stage of its formation may be about 1/150 of an inch in length & 1/1500 in breadth, but these are by no means regular. The external investment at first appears only as a bright line of homogeneous substance best defined on the side next the sarcous matter. It soon however increases in thickness, & afterwards becomes converted into short fibres which increase in size & distinctness as the animalcule grows larger. These fibres are peculiar, there
