Cell Nest 3. This nest apparently is a small nest in di- 

 ameter but it has four "chromatic cells," which indicates that 

 it is somewhat degenerating.

Cell Nest 4. This was a nest with a necrotic center .125 

 mm. to .1125 mm. in diameter, while around this on the edge 

 of the nest was a zone of cells varying in width from .05 mm. 

 to .037 mm. which was undegenerate and which constituted 

 the number of cells counted, so that the total number of cells 

 counted does not show the real size of the nest in point of num- 

 ber of cells, one-half of the area of the nest being degenerate.

Cell Nest 5. This was one of the smaller sized nests and 

 was quite vigorous, showing no degenerating cells at all.
