184 MUNSON. [Vol. XV. 



A high magnifying power shows the body to consist of the 

 following parts : first, a round central body, surrounded at a 

 slight distance by a circle of microsomes (Fig. 45). From this 

 circle radial fibers pass out in all directions to another circle 

 of rather large microsomes (Fig. 47). Outside of this again a 

 dense layer exists, which can be seen to consist either of gran- 

 ules or of closely interwoven fibrils, which radiate out into the 

 cytoplasm, and send larger or smaller strands out along the 

 outer wall of the germinal vesicle. In Weigert's picro-car- 

 mine, in which the circles of microsomes, as well as the dense 

 fibrous layer, are very distinct, the central granule is not vis- 

 ible. This, however, can be distinctly seen in the carmine and 

 Lyon's blue (Figs. 42-44). After the disappearance of the horns 

 of the crescent, the body appears essentially as before. In 

 Lyon's blue it is a large blue mass of fibers, with a somewhat 

 darker center, situated close to the germinal vesicle, and nearly 

 equal to it in size (PL XIV, Fig. 40). It is flattened or slightly 

 concave next to the germinal vesicle ; and it is surrounded by a 

 clearer zone, which is traversed by radial fibers that pass out 

 into the cytoplasm, where they become lost in the red cytoplas- 

 mic network. Stained with haematoxylin, followed with picric 

 acid, the cytoplasm and the contents of the germinal vesicle 

 stain a deep blue ; the body, on the other hand, appears yellow- 

 ish (PI. XIV, Figs. 45, 46). It is seen to consist of granules 

 somewhat closely packed at the center, but less closely packed 

 at the periphery, where the granules are seen to be connected 

 by the same substance as that of the cytoreticulum, into which 

 it passes by imperceptible gradations (Fig. 46). Eggs of the 

 same size as this, however, may show the typical form described 

 above. The indentation next to the germinal vesicle may, how- 

 ever, be so marked as to cause the central granule to lie close 

 to the germinal vesicle (Fig. 45), but yet distinct from the lat- 

 ter, as is clearly seen by the differential stain of Lyon's blue 

 and carmine. At a somewhat more advanced stage, however, 

 the body may be seen about midway between the germinal ves- 

 icle and the periphery of the egg (Fig. 49). When stained in 

 Lyon's blue and safranin, all parts of the egg, except this body, 

 take the red safranin stain. The body, however, appears as a
