Distribution of acid and alkaline phosphatases during the period from late July to August in the kidney and epididymis of the intact and castrated lizards was studied. In the kidney of normal males, the reaction of acid-phosphatase was strongly positive in the epithelium of the preterminal and terminal segments of urinary tubules, and of the collecting tubules. The epithelium of the epididymal tubules, especially in the head of epididymis, also showed positive reaction. In the epithelial cells of these parts the distal portion of the cells and the secretory granules therein contained yielded the strongest phosphatase reaction. The spermatozoa in the lumen of the epididymal tubules and the secretory granules in the epithelium of the body and tail of epididymis were also positive in reaction. The glomeruli and the erythrocytes were weakly positive. In the castrated males, the said portions of the kidney and epididymis underwent a gradual atrophy and ceased to from characteristic secretory granules as Takewaki and Fukuda ('35a) reported. Concurrently with this change, the acid-phosphatase reaction was annihilated, positive reaction having been taken place only at the distal part of the shrunken epithelial cells. The strong reaction of alkaline-phosphatase occurred at the distal part of the epithelial cells of proximal portion of the urinary tubules in the normal lizards of both sexes and in the castrated males. Through the distal portion of the tubules the reaction took place with decreasing intensity. Very weak alkaline-phosphatase reaction was obtained only in the nuclei and in the basement membrane of the epithelium of the preterminal and terminal segments of urinary tubules and of the collecting tubules in normal males. After castration the reaction was reduced in strength still further. The glomeruli and the erythrocytes stained weakly both in the normal and in the castrated males. In the female kidneys, the distribution of phosphatase in the distal portion of the urinary tubules and in the collecting tubules was almost the same as in the kidneys of the castrated males.
