From the results of comparative observations on the gill epithelium of Oryzias latipes, found in both fresh and marine water by chance, or reared experimentally in salt waters, it may be concluded that the adaptability of this fish to salt water is closely connected with the existence of the so-called chloride cells. The conceivable grounds for this conclusion are as follows: 1) The higher the chlorinity of the rearing water is, the greater is the number of chloride cell. 2) As is usually seen in glandular cells during the period of activity, the nucleus is located near on the base of each chloride cell. 3) Vacuoles are very often found in each chloride cell, their form resembling intracellular canaliculus of some kind of glandular cells, and such a mechanism suggests the ability of chloride cells to have the excretory function as is the case with the contractile vacuoles of some Protozoa.
