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

the muscle be put into water for a short time, the cysts will become re-distended, & rendered as apparent as before. As often as these cysts lose their fluid by exposure, they can be re-distended by a fresh appli cation of moisture even after they have been deprived of life, shewing that this property of imbibition of fluid is obviously due to physical causes. These entozoa vary very much in size according to their various stages of development, but the relative dimensions of the white opaque portion, & the transparent sac differ most in those individuals which may be considered to have attained the adult state. Wherever they occur, they are contained in sacs formed by the condensa tion of the surrounding tissues, whose strength & completeness vary in proportion to the closeness of the muscular fibres between which the cysts are found; hence in the substance of the muscular walls of the ventricles of the heart, these adventitious sacs are strong & well defined, whilst they are thin & sometimes indistinct where the mus cular fibres are less closely connected together; or when the cysticerci are situated between a muscle & its fascia, however in all situations they can be easily dis tinguished by the microscope from the true cyst of the animalcule, their structure being very dissimiliar. If the adult Cysticercus be subjected to slight pressure the opaque globular- looking
