We extract the following from the British ■Trade Journal, May 1 : —A. new signal light, possessing remarkable properties, has recently been patented, and is about to be introduced, under the name of "Holmes' patent inextinguishable self-igniting marine and storm signal light.'' The illuminating power is produced by the contact with water of a chemical compound enclosed in an air-tight chamber. Tne mixture is decomposed, and a highly inflammable gas is generated, which ignites on contact with atmospheric air. This chamber is a cylinder 4 in. high by 3 in. in diametfl*, and through the centre of which a tube £ in. in diameter passes, open top and bottom. The tube has numerous perforations in the portion within the chamber. The top of the lube is covered over with a suitable conical-shappd nozzle, having an opening in. in diameter for the emission of the gas. The lower end of the tube, which projects some 4 in., is open for the admission of the water into the chamber, when the lamp is prepared for nse. Both these orifices are hermetically closed by soft metallic caps soldered down, after the body of the lamp has been chai'ged, and in which airtight condition it will keep for years. On using the lamp the soft metal caps are easily removed by means of a knife or the finger, in order to give the necessary specific gravity to the lamp in water, a wooden fiatboavd is fitted to each, and is so contrived that on throwing the lamp into the water it assumes an upright position. When the lamp is in use the water enters by the bottom of the tube, and passes through the perforations into the chamber, deoomp fitng the chemical compound. The evolved gas also passes through these holes, by pressure is forced through the nozzle, and inflames upon contact with the external atmosphere, producing a most powerful and brilliant light, fully fifteen times better than that of the best gas. The flame thus given off ig some 18 in. in height, and burns with an equal intensity over a space of five minutes. The light then becomes gradually reduced in intensity as the internal pressure in the chamber is relieved, the gas giving off a bril iaiit flame some G in. or 7 in. in height, which continues burning for 30 or 40 mmuteg. The light thus produced is inextinguishable by either wind or water. The peeu.iarly brilliant nature of the light, and the subsequent duration of the flame over so long a period of time, give great vaiuo to the patent. These lamps £U*e constructed so that when once used they may be cast aside as valueless. The chemical porhpound employed is phosphuret of calcium, chalk busnel with phosphorus.
