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

surface of about three fourths of a circle in extent, so that the passage through a sucker from the external surface to the interior of the neck is rendered rather tortuous, & inclining to a spiral. The external opening of this passage varies very much in different cysticerci, both in size & shape; but it is always smaller than the internal one. It is difficult if not impossible to demonstrate by the microscope alone, the existence of a passage through a sucker, however, this fact admits of proof from the circum stance of the carbonic acid, which is evolved in the cavity of the neck from the decomposition of the calcareous bodies, when these animalcules are in acetic acid, being seen under the microscope to pass freely through the openings in the suckers. In the membranous folds of the suckers both circular, & radiating fibres are distinctly visible, resembling in their general characters those in the neck already mentioned. See Plate 1. fig: 4. The hooklets as before observed, are situated in a circle around the centre of the square space before described, see Plate 1. fig: 2 & 5. They are generally twenty-six in number, - thirteen long, & as many short, arranged alternately, a long and a short one. Occasionally, but very rarely, there are more, I have seen as many as twenty-nine. The longer hooklets
