I am a hardener of steel, and am composed of steel, and of iron, and of other metals. I am capable of forming a good cement, and of becoming a good conductor of heat. I am serviceable to the sportsman, and to the naturalist, and will even take an impression of a coin. I will bend, and I will also expand. I will form a shape, and I will retain one. I will make you a good servant, and will not injure you by heat, to which I will gradually impart a great part of the heat you may acquire from animal bodies. I will protect you from other sources of heat, and will prevent the pain from arising from the gradual heating of the metal with which you may be connected.
