Paper Electric Insulator.

An Electric Insulator is now constructed of paper pulp. Liquid silica, or silicon, is used as a cementing agent, and when these constituents are combined in proper proportion, a superior insulator is said to be produced, covering, at once, all the ground heretofore almost monopolised by the different forms of glass. This improvement is the subject of a patent recently granted to Chas. C. Hinsdale, Cleveland, Ohio.
