40 _ ·- FEDERAL REPORTER. 3 Ban. & A. 485. As a matter of fact, in this view, it clearly enough appears that corsets of this design would be readily distinguishable by ordinary persons from those of any prior design. The patent appears, therefore, to be valid. Infringement is not disputed, and is clear; so clear that it shows the results of copying. The orators are, therefore, entitledto a decree. , V g ‘ A .Let a decree be entered that the patent is valid; that the defendants infringe; and for an injunction and an account according to the prayer of the bill, with costs. ‘ _ I Wmnmno v.

Welling, ` obtained, a decree sustaining reissued letters patent No. 5,940, dated June 30, 1874, for an improvement in artificial ivory. See 12 Fed. Rep. 875. The defendant, John H. La Ban, having made and sold cer- tain articles containing the patented composition, viz., shellac and talc, in substantially equal parts, was adjudged an infringer, and a master was appointed to take the account.
