the flocks, and gnawing dead bodies in their graves. While every day's experience adds some new proof of the influence possessed by the imagination over the body, the supposed effect of contagion has become a question of doubt. Lately, at a meeting in Edinburgh, Professor Dick gave it as his opinion that there was no such thing as hydrophobia in the lower animals: "what went properly by that name was simply an inflammation of the brain; and the disease, in the case of human beings, was caused by an over-excited imagination, worked upon by the popular delusion on the effects of a bite by rabid animals." The following paragraph from the "Curiosities of Medicine" appears to justify this now common enough opinion:--"Several persons had been bitten by a rabid dog in the Faubourg St. Antoine, and three of them had died in our hospital. A report, however, was prevalent that we kept a mixture which would effectually prevent their fatal termination; and no less than six applicants who had been bitten were served with a draught of colored water, and in no one instance did hydrophobia ensue." A remarkable cure through a similar aid of the imagination took place in a patient of Dr. Beddoes, who was at that time very sanguine about the effect of nitrous acid gas in paralytic cases. Anxious that it should be imbibed by one of his patients, he sent an invalid to Sir Humphry Davy, with a request that he would administer the gas. Sir Humphry put the bulb of the thermometer under the tongue of the paralytic, to ascertain the temperature of the body, that he might be sure whether it would be affected at all by the inhalation of the gas. The patient, full of faith from what the enthusiastic physician had assured him would be the result, and believing that the thermometer was what was to effect the cure, exclaimed at once that he felt better. Sir Humphry, anxious to see what imagination would do in such a case, did not attempt to undeceive the man, but saying that he had done enough for him that day, desired him to be with him the next morning. The thermometer was then applied as it had been the day before, and for every day during a fortnight--at the end of which time the patient was perfectly cured.
