PLATE II. 



FIGS. 15-18. Late prophases of primary spermatocytes showing eighteen large 

 chromosomes, the accessory a little off to one side and the conspicuous chromatoid 

 body anywhere in the cytoplasm. Fig. 16 shows a characteristic bunch of chro- 

 mosomes in which a count is impossible. 



FIGS. 19-26. Metaphase of division in primary spermatocyte, showing the 

 accessory chromosome in characteristic positions passing to the pole, and also the 

 chromatoid body. Figs. 20 and 26 show the chromatoid body with the accessory 

 on the same side of the equatorial plate. Figs. 23 and 26 show also an extra small 

 body.
