Abstract: The teleost scale is one of the calcifying tissues lying in the dermal connective tissue.Since its availability in the age determination of fishes was proposed by Hoffbauer in 1899, the scale has long been subjected to the interest of many fisheries biologists.A considerable number of investigations concerning the structure, the chemical organization, and the growth mechanism have been carried out for the purpose of finding a scientific basis for a possible relationship between the scale pattern and the life history of fishes (Green and Tower, 1901;Taylor, 1916;Paget, 1920;Neave, 1940;Dietrich, 1953;Lindahl and Wallin, 1955; Wallin, 1957; Yamada, 1961; Moss, 1964).However, the knowledge so far obtained seems to leave still much to be solved.According to these previous works, the teleost scale is composed of two different layers, an upper calcifying bony or osseous layer and a lower uncalcifying fibrillary plate.A study on a fish scale of such a peculiar structure as having either calcifiable and uncalcifiable components, could also provide a clue to the general rule for biological calcification, that has long been seeked for because of its importance to the dental and medical sciences.Keeping these points in mind, some histochemical and electron microscopic observations of growing scales have been made in this study, because only little information can be available through these approaches (Wallin, 1956(Wallin, ,. 1957;;Yamada, 1956 Yamada, , 1961;;Cooke, 1967).We wish to express our hearty thanks to Professor Shinjiro Kobayashi for his invaluable suggestions and
