The Telautograph.—A new system of electric transmission was recently exhibited in New York and Chicago which promises to rival in commercial importance the telephone. This is the writing telegraph of Prof. Elisha Gray. By means of it any one can with an ordinary lead pencil on ordinary paper write a message or make a sketch and have it reproduced with exactness, in its minutest detail, in the receiving instrument, which may be hundreds of miles away. As this method of communication necessarily provides a record, and as the mistakes so easily possible in any system of oral communication can not occur, it should find a wide field of usefulness in the business world. Fac-simile telegraphs are almost as old as the art of telegraphy itself, but no such system has heretofore come into extended use, as they have proved unreliable in practice and have lacked the simplicity essential in any apparatus designed for general use. Nearly all previous attempts to provide autographic reproduction have depended upon synchronism
