spindle appearance being due to the rather definite arrangement 

 of the fibers with reference to two poles (PI. XV, Fig. 65). 

 At one of these poles appears a structure consisting of con- 

 centrically arranged microsomes, from which radiate in a 

 somewhat irregular manner protoplasmic fibers. 



In many cases the conspicuous, definitely limited spherical 

 body, enclosing a central structure or nucleus, is seen to be 

 surrounded by a definitely limited zone of protoplasm and gran- 

 ules that differ somewhat from the rest of the cytoplasm (PL 

 XV, Fig. 71). The investing, interwoven, or concentrically 

 arranged fibrous protoplasm, which so frequently surrounds the 

 central nucleus or body, and which makes the whole so con- 

 spicuous when properly stained, is often limited in amount, or 

 €ven apparently absent. The body may then be a spherical 

 granular mass enclosed by a thin definite membrane. There 

 may be two of these situated close together. They are 

 made conspicuous by means of acid fuchsin or eosin (PL XV, 

 Fig. 66). 



As the egg grows the cytoplasm becomes more and more 

 granular, and the body is less easily traced. The peculiar 

 fibrous protoplasm, which often renders it so conspicuous, 

 becomes less and less apparent. It often appears as a spherical 

 mass of granules surrounded by a zone, in which they are few 

 or entirely absent, and around which is another zone of similar 

 granules. These granules being larger than those of the cyto- 

 plasm, and reacting differently towards stains, the body is still 

 conspicuous (PL XVI, Fig. 102). With continued growth of 

 the egg the body often attains to considerable dimensions. It 

 may be a definitely spherical body surrounded by a clear ring, 

 which, in connection with its deeper stain, sets it off conspicu- 

 ously from the rest of the cytoplasm (PI. XVI, Fig. 109). Or 

 it may be irregular in outline, rather star shaped, granular, and 

 may contain within it a spherical central body which alone often 

 comes prominently into view (PL XVI, Fig. 114). This may 

 be situated in the center of the egg and near to the germinal 

 vesicle (Figs. 103, 104, 114). It varies, however, considerably 

 in size ; and it is at this stage difficult to differentiate it from 

 the rest of the cytoplasm. Repeated attempts with a variety
