4 nat. size. 
C and E. Micrococci-like bodies developing in or on the pri- 
mordial utricle in cells of one of these Apples. 
D and F. Similar bodies in other cells giving rise to thread-like 
growths, after the fashion shown more plainly in fig. 4, A, 
G. Larger body of the same kind from which a small hypha is 
developing. 
H. A group of small Torula cells. 
J. Minute branching and interlacing filaments containing rows 
of spores or cocci-like bodies in or on the primordial utricle 
of another cell. 
C, D, EH, F, G, H, each x 700; J, x 875. 
Fig. 9. A. Caudal plumose spines of a recently dead Cyclops quadricornis 
showing homogeneous protoplasm within. 
B. One of the same spines after four days showing motionless 
Bacteria developing within the protoplasm.

Fig. 10, A. Granules and nuclei from disintegrated cells of a sheep’s 
kidney after exposure to conditions described in text for 
thirty-six hours. 
B. Disintegrated: portions of cells from another sheep’s kidney 
which had been exposed to similar conditions for three and 
a half days—now swarming with Micrococci and Strepto- 
cocci. 
Both specimens had been teazed in a weak solution of 
gentian-violet, and both were x 700.

kidney. 
B. Stained portion of the same kidney, showing the thickness 
of its capsule as seen under the same magnification.
