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

there; there is nothing that I am acquaint= ed with analogous to them. They have not the sharp, & well defined outline of true cilia, nor are they pointed like setae, or curled like cirri. They have somewhat the nature of white fibrous tissue, their distinctness being imposed by acetic acid. They are of different lengths in the same entozoon, & general= ly longer, though not thicker in the large, than in the small ones. Their length averages about 1/2100 of an inch. The most remarkable circumstance con= nected with them is the great uniformity of their arrangement in different cysti= cerci. See Plate 2. fig: 2 & 3. They cover the whole of the outer surface of the investing membrane, & on opposite sides of the same entozoon, their form, size, & direction are similar, so that the two halves taken longitudinally are in this respect symmetrical. If the direction of these fibres be examined about midway between the two extremi= ties of one of these animalcules they will be seen to project from the surface at right angles with the axis of its body: but if traced each way from this point they will be observed gradually to incline to this axis at an angle which keeps diminishing as they approach the two extremities, so that the fibres nearest to the two ends almost coincide in their direction with that of the axis, & thus correspond
