The author studied on the morphological property of the fish-blood mainly from a biological point of view; namely red-corpuscle, white-corpuscle, platelet, hematocrit, hemoglobin, cytochrome (Nadi-reaction) and Fe content of several fish-blood were determined. The results were summarized in Table 1-3 and by these studies following phenomena were observed. The blood of migratory fish such as tunny, bonito and mackerel contained more red-corpuscle and its size was smaller than that of bottom fish and consequently the surface of red corpuscle in the former was magnified. The hematcrit value, hemoglobin and Fe content of blood were greater in the active fish than that of blood in inactive one. It was thought that these property showed the nature of fish connected with their activity and the degree of evolution. The blood of shark contained very large red-corpuscle and its number, hematocrit value, hemoglobin content were very few. The platelet and white-corpuscle of fish-blood was very unstable. The polimorphy was most numerous in the white-corpuscle, basiphils wanting in many fishes. The morphological property of fish-blood was more primitive than that of human, and the shark-blood had peculiarity in many respects.
