A TELL-TALE PAINT.

A,red paint, which grows darker in tint as its temperature rises, until at 180 deg Fahr, it is quite brown, was proposed for use as a heat tell-tale, ror if ths lieariugs of an engine are painted with it, the man in charge can tell if they are running cooler hot. The heating of electric wires could also be told. If a scale of tints for comparison, with''the corresponding temptatijres marked upon it, had been also employed, it would have been useful, as the paint is sajfi to regain its original colour on cooling. COCAINE IN HORSE-FIRING. The operation of firing horses is known to be a very painful one; and it is satisfactory that it has been rendered painless by means of a hypodermic in,jeotion_of cocaine. A ten per cent solution of cocaine was used, and although the horse winced slightly under the injection needle, it bore tho subsequent firing without signs of pain. Ow- • ing to recent advances in the manufacture of the alkaloid in England from the Erythroxylon coca, the price of the quantity required for tlje operation in question would not be particularly high.
