Experiment 3.
Three drops of the oil of tobacco were rubbed upon the tongue of a full-sized, but young, cat. In an instant the pupils were dilated and the breathing convulsed; the animal leaped about as if distracted, and presently took two or three rapid turns in a small circle, then dropped upon the floor in frightful convulsions, and was dead in two minutes and forty-five seconds from the moment that the oil was put upon the tongue.
