Histochemical and electron microscopic studies were made on the canal epithelium of the body segment of the rabbit epididymis and following results were obtained. 1) .Acid phosphatase activity was marked in the canal epithelium. especially of the proximal body segment of the epididymis. Granules reactive to the acid phosphatase were present in both the above and below the nucleus 2) Electron microscopic finding: Canal epithelium of the body segment of the rabbit epididymis consisted of largely principal cells. Very few light and few basal cells. Principal cells were characterized by having slender microvilli (stereocilia). Luminal vesicles and vacuoles, extensive Golgi areas and many dense bodies in the supranuclear region, remarkable endoplasmic reticulum of mainly agranular type throughout the cytoplasm. Infranuclear cytoplasm contained often abundant mitochodria, many dense bodies and significant amount of granular endoplasmic reticulum. Light cells were characterized by having light cytoplasm, numerous vesicles, many vacuoles and dense bodies. Basal cells were present characterized by haying small nucleus, small number of cell organelles and rather clear cytoplasm From these results, it is suggested that the principal cell may have dual function of secretion and absorption and the light cell may engage mainly in absorptive function.
