PLATE 8 
EXPLANATION OF FIGURES 
Oogonial growth period 
95 Leptotene threads forming from the chromatin masses following the last 
spermatogonial division. Chromatin nucleoli plainly visible. 
96 Further spinning out of the chromatin masses to form leptotene threads. 
97 Typical nuclei of leptotene stage. 
98 and 99 Transition of the leptotene threads into loops in the formation of 
the bouquet stage. 
100 The typical, loose bouquet stage. 
101 Synizesis stage. 
102 to 104 Stages in the breaking up of the synaptic threads to form the 
faintly staining, anastomosing chromatin masses, characteristic of later stages. 
105 Typical egg which has passed through the preceding stages and is rapidly 
increasing in size. Chromatin nuclei are usually very irregular and woolly.
