A strip of human skin was placed in one section over the frog skin, but became necrotic in four days, not being attached to the granulating surface.

The man was discharged cured in six months.

The frog skin was soft, pliable, and of a reddish hue, while the human white skin was firm and rapidly becoming pigmented.

Leale cites the successful use of common warts in a case of grafting on a man of twenty who was burned on the foot by a stream of molten metal.

Leale remarks that as common warts of the skin are collections of vascular papillae, admitting of separation without injury to their exceptionally thick layer of epidermis, they are probably better for the purposes of skin-grafting than ordinary skin of less vitality or vascularity.
