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

of fibres next make their appearance, the radiating & circular, which have not at first the sharp outline which they after- wards acquire but still appear obscurely granular. As the tissue of these organs possesses nothing characteristic like that of the parts just described, the progressive changes which they undergo during the different periods of their formation can be but imperfectly distinguished; & hence no further description of them will be ne= cessary. It has been observed in respect to the two sets of organs above described, that their size does not increase materially after once formed; exactly the reverse is the case with the part called the neck, also the quantity, though not the size of the laminated bodies which increase in number as the cavity of the latter increases in size. These bodies appear as soon as the hooklets & suckers, & they are as large when first formed as afterwards, but there are indications of the transverse wrinkles of the neck before either hooklets or suckers can be distinguished. See Plate 4. figs: 2 & 3. The neck afterwards continues to grow, so that its relative length in respect to the ventral portion is an indication of the age of a Cysticercus. It is probable that this part does not arrive at its full size until it is protruded, which I have never seen to be the case in any
