A true vivisector is never at a loss to invent excuse or occasion for an experiment. Dr. Brachet had made it clear that a dog will not manifest antipathy toward an enemy whose presence it cannot perceive; but suppose such a mutilated creature, in its darkness and silence, were subjected to some sharp and continuous physical pain, what then would happen? He proceeded to ascertain: "EXPERIMENT 163.--I began the experiment on another dog by putting out its eyes [par crever les yeux], and breaking up the internal ears. Ten days later, THE SUFFERING OF THE ANIMAL HAVING APPARENTLY CEASED, after assuring myself that it could no longer see nor hear, I made a sore in the middle of its back. EVERY MOMENT I IRRITATED THIS WOULD BY PICKING IT WITH A NEEDLE [a chaque instant j'irritai sa plaie en la piquant avec un aiguillon]. At first the dog did nothing but yelp and try to escape, but the impossibility of this FORCED HIM UNCEASINGLY TO RECEIVE EXCRUCIATING PAIN; and finally the dog passed into a state of frenzy so violent, that at last it could be induced by touching any part of its body.... The dog had no reason of hatred against any individual; ... both sight and hearing had been destroyed; and many persons the animal had never seen, provoked its rage by irritating the wound." Of such an abominable experiment, however scientific it may appear, it is difficult to speak with restraint. To the average man or woman it will probably seem that nothing more fiendish or cruel can be found anywhere in the dark records of animal experimentation. Dr. Brachet was no obscure or unexperienced vivisector. At one time he was the professor of physiology in a medical school; he was a member of many learned societies at home and abroad. But think of an educated man procuring a little dog and deliberately putting out its eyes; then breaking up the internal ear, so that for many days the animal must have endured excruciating anguish from the inflammation thus induced; next, when the pain had somewhat subsided, creating a sore on the back by removal of the skin; and then, after comfortably seating himself in his physiological laboratory by the side of his victim, scientifically picking, and piercing, and pricking the wound, without respite-- constantly, without ceasing--until the blinded and deafened and tortured creature is driven into frenzy by torments which it felt continually, which it could not comprehend, and from which, by no exertion, it was able to defend itself! Think of the scientist asking many other learned men to join him from time to time in the experiment, and to take part in picking at the wound, in tormenting the mutilated and blinded victim, and in driving it again and again to the madness of despair! Does anyone say that such an experiment could not be made to-day? In one of the largest laboratories of America, and within ten years, an experiment equally cruel, equally useless, has been performed.
