Investigations were carried out on the effects of light alone not having been affected with the variation of amino acid. The result obtained 2 weeks after the start of experiments was that the hair weight was most heavy under the natural light and next came those under the lamp light and the darkness in order. However, the weight had changed in the order of the lamp light, natural light and darkness after 3 weeks. The hair weight was heavier in the order of the lamp light, natural light and darkness, although it showed an almost same trend in the final stage. Despite the similar growth condition of rabbits under the natural and lamp lights, the body weight had slightly decreased under the darkness. The hair quality of rabbits on the final day of experiments was observed by a scanning electron microscope. A distance between the epidermis scales was most wide under the hamp light. Under the natural light it was wider than that under the darkness.
