Archive Biologist. Nauk 1903, No. 1, Volume X.The author describes one tumor of a sour-yellowish color, the size of a large chestnut, which was, as it were, interspersed into the kidney. A very detailed histological examination is reduced to the fact that the tumor in the center is the usual structure of the adrenal gland and along the periphery it has an epithelial character (papillary and alveolar adenoma). The author refers this tumor to the tumor, which is described by Gravitpem under the name "strumae lipomatodes aberratae renis" and, like Chiari, gives great diagnostic significance to the presence of special pigment cells in this tumor.

Archive Biologist. Science. Volume X, No. 1.Like Delezenne, the author succeeded in obtaining a neurolytic serum by immunizing ducks with an emulsion prepared from the brain and spinal cord of a dog. During his experiments, by the way, it turned out that the specificity of the serum pretty soon (20-28 days of the last injection) disappears. With regard to histological studies, the author notes the changes in the brain 1) with injections of normal duck serum, 2) with injections of neurolytic serum, and 3) changes in the pieces of the brain during the direct action of both serum on them in vitro.
