Leukocytic infiltration is present in the earlier stages, but afterward disappears. The tumor-cells contain spores of the plasmodiophora; the older the cells, the more numerous are these spores. Giant cells are present in places. The presence of karyokinetie figures in some of the spore-containing cells proves that the spore can induce cell multiplication. The appearance of the cells suggests active phagocytosis. The spores in the protoplasm of the cells are surrounded by minute fat droplets, and such cells appear to consist of a large number of vacuoles, each vacuole being surrounded by fat droplets. In a very malignant sarcoma of the abdomen, kidney, thyroid, and other organs, in a child, the author found similar large, vacuolated, fatty cells. Minute inclosures were found in the vacuoles. The phagocytosis in the tumors produced by the plasmediophora in guinea-pigs and rabbits seemed to be sufficient to arrest the growth of the tumor and to prevent its becoming malignant. As no illustrations are given, we must wait for the authors final report before forming a definite judgment concerning his alleged discovery; but even if the parasite produces a formation of new tissue, it may be only a peculiar form of granulation tissue, far removed from a true malignant tumor. 1Centralbl. f.
