U. S. Consul-General Guenther, Frankfort, Germany, reports a newly invented "milk stone," or galalith, or petrified milk. It is manufactured from skim milk in the following manner : - By a chemical process the casein is precipitated as a yellowish brown powder, which is mixed with formaline. Thereby a hornlike product is formed called milk stone. This substance, with various admixtures, forms a substance for horn, turtle-shell, ivory, celluloid, marble, amber, and hard rubber. Handles for knives and forks, paper cutters, crayons, pipes, cigar holders, seals, marble, stone ornaments, and billiard balls are now made of skimmed milk. The insolubility of galalith, its easy working, elasticity, and proof against fire, make it very desirable. Already 20,000 quarts of skimmed milk are daily used for this purpose in Austria.

Outside illumination at the St. Louis World's Fair is to be carried out on a grand scale. The contracts provides for 300,000 incandescent lamps for lighting the exhibit places, grounds, and architectural features of the exposition proper, but not for state, national, and private concession buildings. Twelve thousand lamps alone are to be placed on the Palace of Education, this affording an excellent setting for night effects. The illumination of the grounds is to be carried out on very-ambitious lines. Each monumental standard will carry twenty four incandescent lamps so distributed that twelve will hang on each arm of the supporting post. The lighting of the inside of the buildings will be accomplished entirely with arc lamps.
