Without attempting per- haps to classify them fully, Oohn has divided the bacteria, according to their shapes, into four groups : First.—Spherobacteria, or the globular forms ( commonly known as cocci). Second.—Microbacteria, short rod forms ( bacterium). Third.—Desmobacteria, long rod forms ( bacilli). Fourth.—Spirobacteria, spiral forms. This grouping might serve in a degree as a classification, but the forms are not constant during all the stages of microbic life. Several authoritative naturalists have attempted to make satisfactory classifications, but none of these are free from objection, because of the still limited knowledge of a positive character, possessed by scientists, on the morphology of these infinitely small Figure 2. A variety of microbes showing the different forms constituting the basis of classifications. (Borrowed partly from Cornil and Babes.) At the present writing, it appears thjat the following classes have the greatest number of followers. They were proposed by Van Tieghem in 1884, who places all the schizo- mycetes in the family of 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 Columbia, Mo : [s. n. ]
