The same process is gone through with the second and third inocula- tions, and the three plates can be laid on benches one above the other in a single moist chamber, or a separate one appropriated to each of them. The moist chamber consists of a large glass box, which is disinfected with corrosive sublimate solution and has a circular piece of blotting-paper moistened with a 1 per 1,000 solution of the same substance laid upon the bottom (fig. 25). The plates prepared as above are left at the temperature of an ordinary room until the individual cultures show them- selves on the surface. These appear in the form of islets.

Sometimes several run into one another, and at times a dotted mass appears on the plate, not unusually in the form of little clouds, all of which vary in figure according to the kind of micro- organism. Under a moderately high power of the microscope the colonies are seen to be sharply defined, and sometimes granular, sometimes fibrous, according to the manner in which the micro-organisms are arranged in relation to one another. If the microbes under observation are pigmented, the individual colonies will appear of various tints, or the colour may be diffused through the gelatine, and phosphores- cence or fluorescence may be seen in single spots. By comparison of all these peculiarities it is possible to isolate.
