The spindle at first lies nearer the anterior than the posterior 
part of the odcyte. As it shortens and condenses it is more often 
found below the middle of the cell, and finally reaches a position 
near the posterior end. A variation in the history of this spindle in 
shown in Fig. 14. In a few cases the chromatin apparently migrates 
en masse toward the equator where it forms a compact, irregular 
mass, leaving the linin extending out at either end as a long strand. 


Fig. 15. Longitudinal section through two oöcytes which are in contact. 
Near the posterior end of the lower oöcyte is a mass of keimbahn-chromatin. In 
the upper oöcyte a spindle seems to be in a stage of disintegration. x 800. 
Fig. 16. Similar to Fig. 15. The keimbahn-chromatin (k) has become ir- 
regular and the upper oöcyte contains a spindle in a later stage of disintegration 
than that shown in Fig. 15. 800. 
The fate of these spindles is no doubt similar to that of the more 
usual type. 
The object of this investigation has thus been definitely attained, 
the conclusion being reached that the ‘nucleolo’ of Sttvesrri is not 
& plasmosome (metanucleolus) which escapes from the oöcyte nucleus,
