having proved recognised the several sources of deception, notably the difficulty of proving in most cases of recovery that a genuine poisoned wound has been received, and he has determined to set aside all possibility of error, at least on this special point, and to ascertain by trials on animals whether any real antidote has yet been brought forward. He has neither asserted nor denied anything a priori, and whether the alleged remedy has been an object of belief with a professional man or the nostrum of an itinerant snake-charmer, it has been treated by him with the same care and fairness; and the result is, that medical men have now definite and tangible facts to offer in reply to any one who may feel disposed to criticise the failure of their practice, or mischievously hint that if another course had been followed in a given case, a better result might have been looked for. 'This is a service to the profession which the profession alone can adequately appreciate. The facts are clearly summarised by the author in a few propositions with which our readers are already familiar. They need not be reproduced in this place. We see with surprise therefore, that Dr. Halford, of Melbourne, experimenting on the poison of a different class of animals, and possessed with the belief that ammonia, injected into a vein, is a specific against the bite of Australian suakes, has allowed himself to use a contemptuous tone in commenting In his eyes, it is evidently an unon Dr. Favrer's results. pardonable sin to demonstrate that an Indian snake no more cure

We hope his readers were not blinded by it into the perilous trust in llieir veins which the doctrine inculcates. This doctrine Dr. Halford puts forth with an imposing flourish of physiology. Quotation alone can do the passage full justice:?"The direct injection of caustic or liquid ammonia, mixed with two parts of water, avoiding the ture is made.

caustic alkali, free to exert its marvellous
influence upon the inspired oxygen, or even possibly upon the poison itself, but certainly upon its products. With such physical truths as guides, let us see the result of practice ; and here I may state that all practice not based on physiology is old woman's avocation, and is fast passing out of date, at least in the old country. Far from the centre of knowledge it may still flourish, but 1delenda est Carthago.'" This is a fail' of and Dr. Halford's specimen logic. The phyphilosophy siology consists in the announcement that ammonia reaches the seat of poison more rapidly, and in a purer state when thrown directly into the blood than when swallowed ; the rapidity few will dispute, the purity many ; but if both points be admitted, the curative action remains as far from proof as ever. It derives no sort of confirmation from Dr. Halford's physiology, nor is there any logical connection that we can discover between the process and the result, unless it be first proved that ammonia is a direct chemical antidote to snake-poison. Illustrating his total want of care in guarding against error, Dr. Halford makes no mention of such a doubt as this, and thus reduces his practice, even if successful, to the position of that empiricism which he so seeks to repudiate. Dr. Fayrer, on the other hand, absolutely disproves that there is any direct antagonism between Indian snake-poison and ammonia, by mixing the two and inoculating dogs with the mixture, the only result being intensified poisonous action. The most, therefore, that can be said for Dr. Halford's position is, that he succeeds by a very hazardous process in waking his patient from the stupor and other results of nervous depresIn our crude vernacular sion.
