Show A New Discovery, M. Trojanowski, a Polish chemist, has discovered what he claimes to be a substitute for gum arable, by boiling one part of flaxseed with eight parts of dilute sulphurio acid in eight parts of water until the mixture, which at first thickens, becomes quite fluid. The compound is then strained through muslin mus-lin aud four times its volume of strong alcohol is added. The procipitate, after being filtered, washed with alcohol alco-hol and carefully dried, produces a clear gum devoid of all taste or odor. Thirty grains, it is said, are a sufficient emulsion for an ouuee of cod liver oil. The valuo of this invention will, of course, depend on how far this new article can be relied on as a substitute for the original, and the cost at which it can be produced for the market. A new shell has lately beeu invented by an Austrian for the purpose of scattering scat-tering oil over the waves during a storm. It is a wooden cylinder, lined with shellac to keep the oil from penetrating pene-trating the wood, and it carries in addition addi-tion a calcium light, which illuminates the water for a considerable distance. |
