THE LOGOGRAPU.

The 1 Engineer ’ for June 7 gives the following description of an instrument invented by a gentleman named Barlow, and exhibited by him at a conversazione of the Institution of Civil Engineers on June 3. This instrument is called the Logograph. It has nothing to do with electricity. It consists of a flat hoard, about 12 x 18 indies, for a stand, on which is fixed a vertical board of about the same size. In the upright board, and near the top, is a hole about one inch in diameter, and into this there is fitted a mouthpiece and a short bit of tube ; at the end of the tube, and just inside the vertical board, is a vibratory disc, about two inches in diameter, stretched between two brass rings parallel with the vertical hoard, and at the back of the board there is a very light flat steel spring, secured by one end. This spring runs across, and is united to the disc, and at the other end carries a small camel-hair pencil, fixed perpendicularly, and charged with ink. Upon speaking into the mouthpiece the disc is put into motion, and with it the spring and attached pencil, causing the latter to move in and out from the vertical board. Under the pencil is drawn a ribbon of paper, similar to those use:! in ordinary telegraphy, and on this slip is described a line of peculiar curves. If anyone talks into the mouthpiece of the instrument while clock-work dra s the paper through, Mr Barlow not only maintains that the mouth writing thus produced is legible and intelligible, hut is said to prove it by reading messages so prepared. Shall we ever have a time when the words of a speaker will he takenklown by logograph, instead of by the shorthand writer I
