The presuni'ptionof from the letters, is not overcome by li.nythil'lg flhown. A -compa.rison ;ofthe two holders..-plaintiff's and defendant's.......leaves,no>roomdi0 Idoubt that the la.tter contains the elements of the former. The use for which the defendant's "tool," as he denominates it, is intended, is unimportant, as is also the manner of using it. The plaintiff is entitled to every use to which his invention may be applied. The defendant cannot have the benefit of the plaintiff's holder, even though he may have improved it by the addition of a bar, back of the stone. It would be unprofitable to discuss ,he law or testimony length The plaintiff must have a decree.
