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

as being most characteristic; also some parts of a handle can be distinguished, lastly the larger pieces, formed obviously by the coalescence of smaller ones, can be seen fused as it were together, in which frequently the joining is so incomplete as to amount to little more than mere apposition of the particles. See Plate 4. fig 9 & 12. The part first formed is the hook; this has at first its internal cavity rather larger than that in the other ones, & there is an irregularity of its outline indicating a want of complete union of its component particles. The handle is formed next; this is more re- markable for its want of symmetry than the curved part. Some pieces of it appearing to be merely applied to another. See Plate 4. fig 9 & 12. Lastly the tubercles are added. Neither the whole nor the parts of a hooklet undergo any increase in size after being once formed, but on the contrary rather suffer a slight diminution. The hooklets of the old Cysticercus are frequently smaller than those of the young ones. But these organs vary a little in different animalcules, being rather smaller in some than in others, but those belonging to the same individual are remarkably regular in this respect. From the facts that have just been men= tioned, the hooklets of the animalcule in question do not appear to be formed according to the plan of cell-development discovered by
