EXPLANATION OF FIGURES 



11 Synizesis, primary spermatocyte; smear preparation. 



12 Synizesis and synapsis stage; here the parallel arrangement of the threads 

 is very clearly seen. 



13 Pachytene stage. The parallel leptotene threads have united into gemini; 

 the chromatoid bodies, K, make their appearance in the cytoplasm. 



14 to 16 Diplotene (strepsineme) stage. The second longitudinal split 

 is apparent along the arms of some of the gemini. 



17 and 18 Postdiplotene stage. Figure 17 is from a smear preparation; figure 

 17 (fig. 84) shows the chromatoid bodies, K, in the cytoplasm.
