There is probably no real distinc- tion other than that those occupied by parasites are maUgnant and those induced by non-living granules are harmless. The cells in question in crown gall are not very large, but they contain several nuclei ( 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 Harshberger, John W.
