Kurzeman says he has patented a new type of car coupling and asks McMaster to send him the addresses of New York railroads so he can contact them. He asks if R.B. McMaster, lawyer, is a brother of McMaster and if he could sell the invention. He further inquires whether T.D. Stetson of New York is a safe man to entrust a patent to and if there exists in the country a Catholic scientific society. :: I-2-a A.L.S. 2pp. 12mo.
