Occa-sionally it obtains a lodgment in thetonsils, appearing in the form of littlehorny, yellowish white masses, occupyingthe follicles, and being frequently arranged in a crescentic or circular causes pricking and dryness of the throat. Microscopically, it appears aslong filaments with terminal gonidia. The protoplasm does not contain Fig. 15.—Oidium albicans, thrush fungusfrom month, x 200 diameters. NEMATODA. Filaria labialis and F. hominis oris are rare forms of nematodeworms, occasionally occurring in man. (b) GASTRIC. In the stomach cavity, Ascaris lumbricoides, Oxyuris v&rmicularis, andvarious larvse of parasites have been found. In the stomach walls, favus,actinomycosis, and anthrax have occurred. These have been already dis-cussed, or will be more fully considered at a later period. (c) ^E, COCCIDIA. These, though common in the rabbit, are very rare in man. They appearin the liver substance as multiple opaque white nodules which micro-scopically contain capsulated bodies composed of granular protoplasm, atfirst homogeneous, but which later forms oval sperms. The capsule has adouble contour, and is highly refractile. They are present in the faeces ofthe rabbit, but their mode of access to other rabbits or to man is unknown. INFUSORIA. Monas pyophil
