¶1The application [by Albert T. Meyer] for patent here in issue relates to a composition for furnace lining ■capable of withstanding a high degree of heat without being chemically affected in the reduction of ores.
¶2The three tribunals below were unanimous in holding that ■the invention is anticipated by a patent issued to applicant in ■1915; hence, to allow the claims of the present application Would amount to double patenting.
¶3The ruling is clearly supported by the record, and the de*581cisión of the Commissioner of Patents is aflrmed, and the clerk is directed to certify these proceedings as by law required.
¶4 Affirmed.
¶5A motion for rehearing was denied May 22, 1919.
