Fisher.) reproductive bodies called spores. The spores are formed in the body of the organism in the shape of small rounded masses, and later the body bursts open and the spores are set free. The spores are known as resting forms and their function seems to be to enable the bacteria to exist through unfavorable conditions. The spores have great vitality and they can be subjected to high temperature and to long periods of drought without suffering from such 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 Hood, George William, 1886-.
