New One Wire Telegraph.

Or. William Duane, professor of physics at the Colorado University, has just been granted a patent for an invention by which a large number of telegraph messages can be sent and returned over one wire at the same time. In the physical laboratory at the university it is said he has had as many as eighteen circuits working in this manner. On any of these circuits the Morse instrument can be placed and used exactly as with the single wire now in use. Dr. Doane’s invention is based on the principle of synchronizing moters.
