Arsenic is what is known as a cumulative drug

Arsenic is what is known as a cumulative drug; it produces no special effect until a good deal is stored up in the system. When enough has been given, the said system revolts, and now, when the dog's eyes begin to look watery, and the mucous membrane lining the mouth may be a little red, you have given enough, and must cease; for a time only if the disease is not subdued in permanence if it be. One last word arsenic is the dernier ressort, and should not be used until other means have failed, whereas some people fly to it when a much simpler treatment would have done all that was necessary.
