tetanus, which are consistent with all the cases stated in their books. It is only justice to those gentlemen who have taken pains to look to the authorities to which they refer to say that the statements which they give of their cases are in the main correct, but not in all their details. The books would be five times their size if they were; but they are in the main correct, when we look to the foreign authorities on which they are founded--“The fit is then succeeded by an interval of calm, during which the senses are impaired or are unnaturally acute; but another paroxysm soon sets in, and then another and another, until at last a fit occurs more violent than any that had preceded it, and the animal perishes suffocated.” I know exactly what Dr. Christison means by this, because there is a gentleman here who will state an experiment which I saw myself; it was an experiment, and for the purpose of this case, and to assist me; and I disagree with Dr. Taylor that there can be a moment’s hesitation in sacrificing ten or twenty dogs for the purpose of ascertaining the truth of this theory when a man’s life is involved. These experiments were performed by Dr. Letheby while I was there. I will state them to you, because he will prove it by and by. A dog had some strychnia put in his mouth, one grain, and then for about--I cannot be sure as to the time exactly, but about twenty or twenty-five minutes--I cannot be sure, it might not be so much--the dog was perfectly well. There were two rabbits on the table which were also about to be subjected to the operation, and the dog, when the chain was sufficiently relaxed to enable him to do so, showed all the indications which a dog naturally does to get at the rabbits; he was pulling at his chain, and was smelling and pawing and taking an interest in the rabbits; suddenly it fell down on its side, and its legs were stretched out in a most violent way. It panted, and then it remained for some time--two or three minutes--quiet, occasionally a little jerking, but generally quiet. It recovered again for a time, got up and looked at the rabbits, but was dizzy, seemed afraid to move; and, if you touched it, shuddered and twitched, to use Miss Elizabeth Mills’ description; seemed to be afraid, and after another moment down it went again. It got up again, and down it went again, and at last it had a tremendous struggle, and it died. That is what Dr. Christison means by this description; it would be true if the dose had been a strong one. If the dose had not been sufficient to kill the dog it would probably be a longer time--at least, I suppose so--in producing its effect, and the interval between the paroxysms, as stated by Dr. Taylor and Dr. Christison, would get longer and longer, until at last the animal would recover. If the dose is strong enough to kill, the interval between the paroxysms is shorter, till at last the violent one comes which destroys life; the eyes are
