Animals have been killed when it has been applied externally. Dr. Duncan killed a dog in twenty-hour hours by applying sulphate of copper to a wound. The symptoms produced by poisonous doses of soluble copper salts are very similar to those produced by arsenic and corrosive sublimate, there are, however, differences which will be noticed presently. Iu copper, as in arsenical poisoning, there are local and remote symptoms. The local are produced by the irritating effects of this escharotic substance. Like arsenic, copper salts seem to adhere to the mucous surfaces and set up inflammatory action. When death takes place slowly, these appearances are more marked. That copper is taken up by the blood, has been proved by experiments on animals, and when acting through this medium on tho system, the heart's action is interfered with--it loses its contractile power, and after death, red blood is found in its cavities.
