Plate XIV. 



Fig. 84. One nurse-and one egg-chamber. From the oöcyte, a process, 

 extends into the nurse chamber. Distal in the oöcyte is the nucleus and near 

 it and on its periphery the small nuclear-like bodies are seen. The proximal 

 end of the oöcyte shows the Strand which extends from the oldest oöcyte 

 Chamber (Paulcke), Oöcyte, oöc, 0,08 x 15 mm. x 100. 



Fig. 85. One of the proximally situated nurse-cells from the nurse Chamber 

 of last figure. Cell diameter 0,03 mm. x 400. 



Fig. 86. Nurse Chamber and part of an egg Chamber, oöc. The breaking 

 up of the nurse-cells is noticed in the partial disappearance of their boundaries; 

 the cells no longer fill out the Chamber. The opening between the two Chambers 

 is seen. Size of oöcyte 18. x 47 mm. x 100. 



Fig. 87. Single nurse-cell from nurse chamber of preceding figure. The 

 cell boundary is drawn more regulär than it should be. x 400. 



Fig. 88. Nurse chamber and parts of two egg Chambers, oöc. The dotted 

 liue in the oöcyte (also in figures 84 and 86) shows the cone-shaped mass free 

 from deutoplasm. x 100. 



Fig. 89. One quarter of a nurse-cell nucleus from one of the nurse-cells 

 of preceding figure. x 400. 



Fig. 90. Parts of two egg Chambers, oöc, and between them the nurse 

 Chamber, with only three nurse-cells, vv^hich belongs to the lower one. x 100. 



Fig. 91. Part of an egg chamber, oöc and two nurse Chambers between 

 which a few epithelial cell nuclei can be seen; these represent all that is left 

 of the missing egg chamber. x 100. 



Fig. 92. An oöcyte nucleus with the surrounding nuclear-like bodies from 

 an oöcyte 0,05 x 0,08 mm. The contents of only a few of the small bodies 

 have been filled in. x 1600. 



Fig. 93. Nucleus and one of the small bodies from an oöcyte 0,07 mm in 

 diameter. x 850. 



Fig. 94. Same from an oöcyte, 0,12 x 0,15 mm. x 850. 



Fig. 95. Same from an oöcyte, 0,14 x 0,24 mm. x 850. 



Fig. 96. Same from an oöcyte, 0,20 x 0,36 mm. x 850. 



Fig. 97. Same from an oöcyte, 0,18 x 0,47 mm. x 850. 



Fig. 98. Same from an oöcyte, 0,29 x 0,47 mm. x 850. 



Fig. 99. Two dividing cells with the chromatin ring between them. 

 X 1600. 



Fig. 100. One oöcyte, a, and one nurse-cell, b, from position just distal to 

 the synapsis nuclei. Oöcyte with two rings. X 1600. 



Fig. 101. Oöcyte in synapsis showing two of the chromatin rings between 

 it and neighboring cells. The darkened cytoplasm extending through the ring 

 has been drawn. x 1600.
