On potato a thin crinkled film is formed, which is yellowish or red- dish-yellow in colour. They occur on potato. Eacillus mesentericus vulga- tus (Flugge).—Rods large and thick, often forming pseudo-threads. They have an oscillating movement. Spore-formation present. The colonies are bluish-white and almost transparent, though the centres become gradually opaque. They sink in the liquefied gelatine, and are granular with irregular contour. Bacillus multipediculus (Fliigge).—Rods long and slender. Non-motile. The colonies consist of a central oval nucleus, from which numerous tapering processes shoot out mostly towards one pole. This form of growth gives a curious resemblance to an insect with feet and antennse. Inoculated in the depth of gela- tine a whitish line forms along the track of the needle, from which short processes grow out. On potato a rather scanty dirty- yellow growth forms, and the sur- face of the potato becomes dis- coloured around it. They are often found as a con- tamination on potato. Bacillus muscoides (Liborius) —Rods 1 /J. thick, sometimes form- ing threads ; slightly motile, and with round or oval spores at one end. They are anaerobic. The colonies ramify and resemble a delicate moss. They were found in the oedema- tous fluid of field mice inoculated with garden earth and stale cheese. Bacillus mycoides (Fliigge).— Rods rather thick, nearly the size of Bacillus anthracis. Motile, often forming long pseudo-threads. Oval and highly refractive spores both in
