nests and thus nearer the necrotic areas than the indirectly 

 dividing cells. 



7. The indirectly dividing cells lie nearer the periphery of 

 the nest than the directly dividing cells. 



8. From these observations it may therefore reasonably be 

 concluded that amitosis represents the final effort of the cell at 

 reproduction, and that shortly after its occurrence degenera- 

 tion ensues. 



9. Amitosis, mitosis and disintegration comprise the cell 

 changes in the alveoli. 



10. Cells in direct and indirect division are larger than the 

 resting cells. 



11. In one stage of degeneration of the cells the chromatin 

 becomes diffused through the karyoplasm and so swells that it 

 fills the nucleus as a deeply staining, homogeneous m^ass. In 

 another process of degeneration the chromatin loses its staining 

 power and the cell becomes clear. 



12. There is a shrinkage of the nuclear bulk in degeneration. 



13. A border of chromatic cells lies between the vigorous 

 cells and the cell debris of the necrotic area and marks the 

 limit of degeneration; such cells are themselves degeneration 

 results.
