"Fowler of Brooklyn has grafted with skin from the back and abdomen of a frog. The patient was a coloured boy of sixteen, who was extensively burned by a kerosene lamp. The burns were on the legs, thighs, buttocks and right ankle, and the estimated area of burnt surface was 247.95 square inches. The frog skin was transferred to the left buttocks, and on the right buttocks eight long strips of white skin were transferred after the manner of Thiersch. 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."
