Dr. Rowland inquired at the patent office in Washington and was informed that no suoh invention has ever been received there, typewriting telegraphy having been attempted before, but upon entirely different principles.

When completed, Dr. Rowland says, the new instrument will be as convenient and as easily operated a» the ordinary telegraphic dispatching and receiving apparatua—St. Louis GlobeDemocrat.
