be seen to have been produced by the pointed ends of the entozoon. These fibrillae having been obviously turned out of their original course & some directed to one side, & some to the other. See Plate 3. Fig: 1. This ex= planation receives confirmation from the fact of those cysticerci, which commence their development in the muscular parietes of the heart, being of a different shape from those formed elsewhere, although their structure in all other respects is precisely the same. These cysticerci in the first or vermicular stage of their development are very short, & thick, & of an oval shape. Their loco= motive fibres though perfectly demonstrable are very short & in many instances im= perfect. See Plate 2. fig 5. This difference might have been anti= cipated considering the close texture of the muscular fibres of the heart, the absence of any well formed sarcolemma, & the shortness of the fibres occasioned by their frequent interlacement, all which circumstances would materially tend to diminish the effect, as well as the ne= cessity for these fibres, & therefore be unfavourable to their longitudinal devel= opment. After these cysticerci have reached the spaces between the muscular fibres, their subsequent development is the same as in other situations, & the perfect animals formed in the heart can not be distinguished from those formed in other muscles.
