Some studies on the colour of meat and Fe content in blood and hemopoeitic organ of several fishes were performed mainly from a biological point of view. The results were summarized in Table 1-3, Fig. 1 and by these studies the following phenomena were observed. The Fe content of the blood of some migratory fishes, as tunny, bonito and mackerel, was larger than that of bottom fish, while that of the shark-blood was very small. The hematocrit value and especially hemoglobin content showed to have acorrelative rilation to the content of Fe in fish-blood. Then the author studied the ratio of the weight of various hemopoietic organs to the body weight and by these studies the liver of shark was found to have very larger ratio of the weight than that of other fish. Generally the kidney of fresh-water fish and the spleen of active fish had larger ratio of weight than any other fish in each case and the Fe content of spleen was larger than that of other hemopoietic organs; and that of each organs in the shark was very small. The Fe content of dark meat (especially the caudual part) was larger than that of white Treat and Nadi reaction in the former was distinct. These contents of the actve fish were larger than that of inactive one. It was provable that these phenomena showed that the colour of meat had some connections with the quartity of the hemoglobin content and the volume of blood.
