diarrheal and dysenteric discharges. Maycause general infection in human beings. With or withoutgeneral infection it may cause hemorrhagic and necrotic en-teritis, a form of pyocyaneous infection in human beings whichwe have repeatedly observed at autopsy. Instances of in-vasion of the body from wounds by the bacillus pyocyaneushave not been observed (Welch). Bacillus of Bubonic Plague.—Morphology.—In the 32f \. PATHOLOGICAL TECHNIQUE. tissues the organism occurs as a medium-sized short bacilluswith rounded /ends. In cultures its size and length varyand its median portion may be swollen so that an ovoidform is produced; it may grow in pairs and in chains,and it may occur as long, thread-like forms. Involutionforms of elliptical or round shape, and often of large size,sometimes resembling yeast-cells, are frequent in old cult-ures or in cultures on special media. These involutionforms are easily produced by cultivation on agar-agar con-taining 2y2 to 3^ per cent, of sodium chlorid.

In thetissues it stains more deeply at its extremities than at itscentral portions, and it sometimes appears to possess a cap-sule. The polar staining may sometimes be brought outin cultures by weak staining solutions or by decolorizationby alcohol. It is not motile, and it does not form spores. • Gelatin Plates.—The colonies on the surface appear aftertwenty-four to forty-eight hours at 22° C. They are flat,rOund, and white or yellowish white in color. Under a lowmagnifying power the central portion of the colony is gran-ular, while the marginal portion is clear. The colonies donot spread over the surface of the medium.
