A simple and inexpensive portable fire escape, which may be packed in small compass to take but little room in a travelers trunk or bag, is shown in the accompanying illustration. It has been patented by Victor Leber, and is manufactured by the Turner Machine Company, of Danbury, Conn. It consi sts of a clamp adapted to slide upon a rope, as shown i n the small figure, the clamping or fricti onal pressure upon the rope being readily controlled by the person using the device. The two hinged parts of the clamp are provided with regi stering half grooves adapted for convenient use on different sizes of rope. and the clamp is held m grippi ng position upon the rope by a threaded lock i n g lever on the outer end of which is a finger wheel. At the top and bottom of the clamp are rings through which the rope passes, affording a slight frictional brake, and at the bottom is also a double hook to which may be attached body and shoulder straps to support one making use of the device in escaping from a building. When the escape is permanently fixed in houses or factories, the rope is preferably attached to a hinged am secured at the inside of the window casing. The device may also be secured to the window casing. When several persons are in one room, the frictional pressure of the clamp may be controlled by one standing in the room to let down different indi-viduals in turn, the looped end of the rope being then secured to the straps by which the person is suspended. and the rope sliding through the clamp. As one person reaches the ground, it is ready for another to descend. Each apparatus is tested to 1,000 pounds before leaving the factory of the manufacturers, and ie whole device is designed to be so simple and fe in its mode of operation that there shall be no iasonable possibility of a person failing to make it ork properly in an emergency. This apparatus iay also be conveniently employed by painters, uilders and electricians, and by all engaged in work ecessitating their being suspended outside build-igs. Remedial Foods.

An important contribution appears in Comptes Rendus, by Heibling, indicating the production of alumina from clay, so as to be absolutely free from silica and readily convertible into sulphate, etc. To this end the clay is thoroughly incorporated with a mixture, in equal parts, of ammonia and potassium sulphates, in such proportion that three molecules of ammonium sulphate may be present to every molecule of alumina, and the mixture is made into hollow bricks, which are then heated in an oven at 270 deg. to 280 deg. C. At this temperature both gaseous ammonia and acid ammonium sulphate are given off, which immediately reacts with the potash salt present, acid potassium sulphate being formed—the latter, at the above temperature, com bining with the alumina of the clay to form aluin. The alum is finally extracted from the bricks by means of water and freed from iron by recrystallizatioii, and the insoluble silica remaining behind may be employed in cements. Granular alumina is prepared by spreading out the powdered alum in a thin layer on shelves arranged in a vertical tower, which is traversed by the warn, moist, ammoniacal fumes derived from the brick oven Thus the alum is transformed in situ into alumina. retaining the forni of the original powder, and potassium and ammonium sulphates.
