 Nurse-cells (n.c.) in nurse chamber with deeply staining cytoplasm. At base of 

 nurse chamber are found young oocytes in various stages of synapsis. I. n.c., 

 region where ingestion of nurse-cells takes place. Products of this ingestion are 

 seen passing down egg-string (e.s.) to the older oocyte (ooct. 2), which also shows a 

 perinuclear zone of mitochondria.
