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.
