WASHINGTON, Circuit Judge.

Appellant Delmar Larsen seeks to obtain a patent, in a suit brought under R.S. § 4915, 35 U.S.C.A. § 63, covering a fluid composition to' be used in the drilling of oil wells. 1 The Patent Office denied the application because it thought Larsen had not sufficiently shown that he had completed his invention prior to disclosure of the composition in the earlier application of a third party.
