The microscope reveals that, like the trichinae capsules, they lie within the sarcolemma, but that the normal appear- ance of the muscle substance is not changed, as the transverse striae can be seen in the periphery. “The granular contents (Fig. 78) of the sac like envelop consist of numerous reniforin bodies which have a great similarity to the spores of certain fungi. The outer wall consists of a clear cuticular layer of tol- erable thickness, and is pierced by numerous porous canals, at least in many cases, while in others the cuticular wall is covered with stiff bristles.” “Psorosperms found by me in dogs appear as pustules of an oval form, with a sharp contour, an almost shell-like capsule, and a few granular bodies. The granular substance was collected into a mass, which did not by any means fill the capsule. The remaining contents consisted of a clear albu- minous substance, which was sometimes drawn together in a stringy or sausage-like mass, so that I was reminded of the egg of p' a nematode. [Berkan (Virch. Arch. 35, p. 1), says: “Psorosperms are found in FlG- 79-—Tyroain crystals in ham from Westphalia all hogs, but in smaller number (Leuckart). in summer, owing perhaps to green food being plentiful at that season. In some cases where hogs were fed on milk he found immense numbers »1 Although these bodies are often found in animals, the subject does not seem to be seem to oe inconven- ienced by their presence.
