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

to leave no doubt of their real nature, it will be seen that the highly refractive globular particles seen in Plate 4. fig 3 are portions of the material of which the hooklets are composed. The entire number of these organs is not in progress at the same time, but only about six are being developed at once, which, when nearly completed, others make their appearance. The primary condition of one of these organs is very remarkable, consisting merely of a confused & irregular group of very bright particles of a pale straw-colour of various shapes but still all have a contour more or less curvilinear, & the smaller ones are of a spherical figure. Their size varies from about that of the third part of a handle of a perfect hooklet, to a particle so minute as scarcely to be appreciable by the highest powers of the microscope. There are all the intermediate sizes between these extremes. Notwithstanding however, these extremes of size & form, all these particles possess the same optical & physical properties so as to be per- fectly recognisable both when apart & when joined together in the perfect hooklet. See Plate 4. fig 4 & 5, in which they undergo no appreciable change in their general ap- pearance. At a period of the development a little more advanced <s>a little more advanced<\s> some parts of a hooklet can be recognised among these various forms, especially the curved portion as fol. 9 Sig 2
