Some inquiries have been made of us respecting the recent Patent Trial India Rubber Case, at Newport, R. I., about which a number of our daily papers have made regular reports without being able to give the least clue to the uninitiated relative to what the trial is about. Some people have thought it not a little strange that Horace H. Day should be the plaintiff in this casejas own er of Chaffee's patent, which was extended by Mr. Ewban-k, and against the legality of which extension Mr. Day issued a long manifesto, subscribed by some distinguished lawyers. We would state that the trial is nol to test the validity of the patent, but is to settle some bargains connected with the inventor and the owner of the patent. The cholera is now raging fearfully in some places of Denmark. In Copenhagen, 300 ditd ot it in one day.
