This is one of the series of interferences mentioned in Prather, v. Tellier, appeal No. 1742, just decided, — App. D. C. —, 5 F.(2d) 1010, and was disposed of on the same testimony and with the same result below. As we have adopted the reasoning and conclusion of the Patent Office in appeal No. 1742, it follows that the decision here must also be affirmed. Affirmed.
