(2) No budding or division of the bodies could be 

 detected with any cei-tainty ; no chains nor diplococci 

 were seen, 



(3) There is a marked tendency for individual cells 

 surrounded by ordinai-y healthy tissue to be pigmented.

while in the case of bacterial infection continuous areas 

 would probably be involved. 

 From these considenitions it may be presumably assumed 

 that the granules in question and the surrounding clear

 living protoplasm. 



Such transformation gradually increases until almost the 

 whole of the tissues may become affected. The masses of 

 granules, whether resulting from one cell or several contigu- 

 ous cells, generally assume an oval shape whatever the 

 original shape of the cell (text-fig. 2, a, b, c). At times the 

 masses run into one another and an irregular reticulum 

 results (fig. d). By this time the tissues affected have become 

 moribund and ultimately perish.
