Healing of the wound involving full thickness of the skin was investigated in carnivorous mammals (cats, foxes, polar foxes). Square wounds (2.2 cm2) were inflicted on the back and the head of cats and onthe thigh of foxes and polar foxes. In all the animals investigated the wounds closed chiefly by contracture of their margins. A small regenerate was formed in the centre of the wounds; its structure was almost the same as that of the intact skin: there were hair and sebaceous glands. Connective tissue skeleton of the regenerate resembled the derma by the fiber distribution.
