This is a bill in equity to restrain the.infringement of letters patent No. 219, 208, dated September 2, 1879, to Charles F. Brush for an improvement in electric lamps. The defendant took no testimony, and did not appear at the hearing.

Rep. 826; of Judge Brown, in Same v. Western Electric Light, etc., Co., 43 Fed. Rep. 533; and of Judge Blodgett upon a motion for an injunction in Same v. Ft. Wayne Electric Co., 44 Fed. Rep. 284.
