CEOWELL V. HARLOW. 141 �From the evidence and the stipulations of the parties, it appeared that the patent was now owned by the plaintiff ; that the method of Atwood had been described to the defendants, and that they had taken licenses from the plaintiff, which both parties understood to be for the term of one year, -which had expired before the bills were filed. At the hearing, it was suggested by the defendants that the licenses might be construed to run for the whole life of the patent, but the answer had not taken this defence.

They fully agree that the patented method is a great improvement upon that before praeticed. If this method were merely to remove more of the bones, or to skin the fish, or both, it would seem to i-equire and prove only the exercise and skill in handling the fish, and taste in making them attractive. So, the packing in boxes is clearly no invention. �The evidence goes further, and proves that Atwood made a discovery; that there is in the fish, to which his invention is applicable, what he calls a mucous membrane, and what others call an inner skin, or a sort of film, and that the re- moval of this memt)rane is not necessarily effected by skin- ning the fish, unless attention is given to this inner skin, and that the presence of this inner skin is highly injurions to the keeping quality of sait fish. It is singular that such a dis- ��� �
