SPONTANEOUS IGNITION.
E. Bing, of Eiga, Switzerland, has (says the “Scientific Anc'iiaa”) exp rimented with different materials —wadding, raw flu, hemp, the waste from silt, wool, and cotton spinnings, as well ae sponge, and finally wood dust as found in any cabinetmaker’s shop. They were saturated with various fluids—namely, oils, fresh and in a gummy state; turpentine, petroleum, various varnishes, &o. All the fibrous materials took fire when saturated with any of these oils, or with mixtures of the same. Sponge and wood dust, on the contrary, proved to be entirely harmless. Combustion ensues, with 17 grains of wadding and 67 grains of a strong oil varnish, in thirty-four minutes ; while 200 grains of washed cotton waste, of which a portion was saturated with 750 grains of strong oil varnish, and the remainder wrapped about it, required almost fourteen hours. These materials were placed in a well sheltered spot, and subjected to a heat of from 40 to 65 Fab. Silk did not flijne up, but slowly charred.
