Cement to Fasten Leather upon Metal.—Soak the leather in a hot solution of nut-galls, and apply it to the metal upon which It is to be fastened—the latter must be provided' with a coat of glue. When dry, the leather will adhere so tight that it will tear before separating from the metal. Harness, and other articles of leather that are injuriously acted upon by the ammoniacal exhalations common in stables, may, according to Prof. Artus, be thoroughly and effectually protected by the addition of a little glycerine to the oil or blacking with which their surfaces are treated. Experiments as to the penetrating power of colored light show that the blues are not visible hall a league off, and should not be used as lighthouse signals. White, red and green lights can be seen the farthest. The green looks like a white light when at a distance, and should be used only in contrast. Dr. Ultzman, of the University of Vienna, in a paper read before the medical society of Lower Austria, on the ‘‘Use of Photography in Medical Science,” said that an eruption of small-pox had been made evident by photography twen-ty-four hours before it actually came out. Although nothing was to be seen unusual on the skin ol the patient, the negative plate showed stains on the face which perfectly resembled the variolous exanthem, and twenty-tour hours later the eruption became clearly evident. Mr. Corvin, of London, in his pamphlet on hydrophobia, indorses the theory of Dr. Thompson, according to which it is a vulgar error that patients in hydrophobia are mad. They are not mad; there is no such thing as madness connected with the disease. The Duke of Richmond, who, while Governor-General of Canada, was bitten by a rabid fox, and suffered from the most violent paroxysms, which ended in death, had sufficient fortitude and self-control in the intervals to give all necessary directions for the conduct of public business and the settlement of his own urivate affairs.
