Cavities have begun to form and additional ones are present beyond C (.right margin), where also are a few cells containing starch-grains (see fig. 106). In various places, as at X (use lens), some change has taken place in the walls of the cells and they are made out with difficulty. In other places, as on the left side, cells which appear to have unbroken walls are occupied by the bacteria. The walls of the cells destitute of starch seem to take the stain somewhat heavier than those of cells in which it is present. Camera drawn, but slightly diagrammatic.

Tissues fixed in Carnoy's solution. Camera drawn, but slightly diagrammatic i. e., it is probable if the slide were taken and compared cell by cell with the drawing, some omissions and some errone- ous lines would be Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
