There is also a stop which jirevents the leaffrom opening bejoud a line straight with tlie handle, whichfurther facilitates its use for inside work. The larger pitchesare so arranged that they can be used as a gauge for grinding tools. ♦ AN ELECTRIC HEATER. Messrs. Lagrange & Hone, two Belgian scientists, arethe inventors of a new method of heating, melting and re-fining metals by means of electrical heat. The apparatusconsists of a glass or porcelain vase of any size conven-iently adapted to the purpose, provided with a lining of leadconnected with a strong conductor of positive is filled to three-fourths its capacity with acidified pair of iron tongs with insulated handles is attached by aflexible conductor to the negative pole of an electrical currentgenerated by an ordinary dynamo. The electrical currenthaving been switched on, a bar of wrought iron or other metalis taken up with the tongs and plunged into the wat
