This is made so by the histological structure of these tissues, in tat they have no pm er of repair and recovery from injuries. The hair, nails, and the continuous growing teeth of a few animals, while having no means of repair of developmental or acquired injuries, dispose of the injured parts by the provision for the wearing away of the substance, and with this
