1. A comparison of the multiple markings labelled on scale, centrum and otolith of young goldfish was made by administering various amounts of tetracycline at intervals of one, two and three months. 2. For obtaining a clearly separate multiple pattern of the tetracycline fluorescence on every tissue of the scale, centrum and otolith of a fish, injections at intervals of more than two months are recommended to be appropriate. However, as for multiple markings on otolith only, injections may be successful even at an interval of one month. 3. A suitable amount of the tetracycline injection for young goldfish is considered to be 50mg. per kg. of body weight. 4. The intensity of the tetracycline fluorescence labelled on the otolith is found to correspond with the dosage administered, but is not always so on both the scale and centrum. 5. Even with the same dosage level administered, the tetracycline pattern on the scale is highly variable according to individuals and also to parts of the fish body. However, the patterns on the scales of central part of the flank along the lateral line was shown to be stable, at least, in the individuals with normal growth of body.
