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

add, that the vermicular form of those cysticerci whose development commences in the short muscular fibres of the tongue are of a shape resembling very much those of the heart. <s>which has just been described as covered with cilia.<\s> The investing membrane which has just been described as covered with cilia, is entirely filled with corpuscles, all of one kind, remarkably characteristic & differ- ing only according to their states of develop- ment. The perfect cells are best seen in the middle of an entozoon, but their mode of formation, & the subsequent chan= ges which they undergo, must be examined in those parts which are increasing most rapidly as in the growing ends of an ani= malcule. The first appearance indicative of an increase in the length of an animal= cule is a thinning of the investing membrane, & a separation or partial detachment of the cilia-like fibres at the growing end. Next a clear space of the form of the part which is about to be added is perceptible a little in advance of this extremity, ap= parently the result of a very fine mem- branous protrusion. This contains numerous dark molecules of different forms & sizes mixed with granules more or less per= fectly spherical, the most perfect of these globular bodies are those which are nearest to the perfectly formed part of
