pushing out from clear area through granules of vitellus. Chromo- 

 somes irregularly placed in a hyaline area. Spindle striae observed 

 in viewing the egg at right^angles to spindle axis.

 Fig. 3 illustrates an optical section of egg No. 1 1 from oviduct 

 of another animal, occupying the same relative position as No. 11 

 in the oviduct drawn. In an eccentric position, and near the 

 surface, a clear circular area with radial striae was observed, indica- 

 ting the presence of the male pronucleus. A portion of the 

 membrane of the germinal vesicle still present. Egg No. 10, in 

 the same animal, also showed circular male area in direction of 

 axis of spindle, and chromatin granules within it. In egg No. 9 

 the head of spermatozoon was seen in optical section, some little 

 distance from periphery, circular with narrow Hof about it, and 

 striae radiating from Hof. Very fine granules were evident within 

 this pronucleus.
