of the animalcule. These corpuscles when completely formed have a bright oily look= ing aspect & a diameter of about 1/8000 of an inch. See Plate 1. fig: 8. These corpuscles have the appearance of being formed by the coalescence of molecules which had existed in the clear space before any corpuscles were ap= parent, by which they are afterwards re= placed. After a growing end has become thus filled with these globular bodies the terminal membrane becomes more & more distinct, & the cilia-like fibres are afterwards added which are generally nei= ther so regularly disposed, nor so distinct as on other parts of an entozoon. Next these corpuscles lose their spherical form & become flattened, & lastly they assume their cha= racteristic elliptical or reniform figure before mentioned (See Plate 1. Fig: 10) which they retain as long as the ento= zoon remains in its primary muscular fasciculus. This shape however is not essential to these corpuscles but merely results from the rounded form of the masses into which they are grouped together, each corpuscle by its convexity forming a segment of the circular outline of its respective mass. These corpuscles contain very fine dark granules so variously disposed in different ones, as to present a variety of appearances, such as circular or oval spaces which might be taken for nuclei or nucleoli.
