With reference merely to pathogenic bacteria, it would suffice to recognise four principal groups—viz.; 1. Micrococci. 2. Bacilli. 3. Spirilla. 4. Bacteria. The term Aerobic has been applied to those bacteria which can only live, or grow where there is access of air; Anaerobic to those where air is excluded—i.e., beneath the surface of the fluid or other nutritive medium. Artificial cultivation is employed to demonstrate certain characters derived from the mode of growth, since the form8 of bacteria do not always afford constant distin- guishing characters, and the form of numerous apparently different species is identical. . cultivation of Bacteria.—Nutrient gelatine is the
