In order to get the electron microscopic criteria for identification of oligodendroglia, the corpus callosum and cerebral cortex of 80-100 gm male rats were impregnated by the modified silver carbonate method of del Rio-Hortega for electron microscopic observations. The opacity of the metal deposits could be recognized in the nucleus and cytoplasm of the impregnated cells. These cells showed the wide variety of cellular sizes. The cells with filaments were not impregnated. Although the metal stained microglia could be also seen, they were excluded by their fine structures. It was found by cell count that the ratio of the impregnated to the non-impregnated cells was 3 : 1. The characteristic features of those oligodendroglia were thus established to be a round nucleus with dark chromatin masses and a cytoplasm containing numerous free ribosomes and rough endoplasmic reticulum as well as other cell organelles.
