These discoveries enabled man to eni j)lay the. Amber Spirit as a courier, a vo. cation for which-he is eminently ■ suited

as the speed at whicu he travels has been estimated at 288,000 miles in a second. . The Spirit in due course was taught to write ; and had no sooner been taught to write, than man set about teaching him the art of printing. Behold him now a lhaster of the craft, printing messages letter by letter in the ordinary Roman characters, under the direction of_ an operator stationed at a distant city ! (Bain's Printing Telegraph.) , The Spirit's education was not yet finished ; he had to acquire another accomplishment. He could communicate intelligence by means of moving needles and revolving dials, by written dots and printed characters, but he could not yet imitate the handwriting of the individual who forwarded the message. An inge nious gentleman now took him in hand, and soon made him an expert copyist. A message was written with a non-conduct ing varnish on a piece of tin-foil in Lon don, and almost as soon as the varnish was dry an exact copy was seen upon paper in Brighton ! The philosopher Thales wondered to see certain minutp bodies fly towards a piece of amber ; but how great would have been his astonishment had some superior intelligence informed him that the invisible agent which moved the par ticles would one day be taught to trace figuras upon paper exactly like those just written on a metallic surface by some one far away ! A hundred systems of communication might bo enumerated in addition to those we have noticed, so great has been the intellectual activity of the last twenty years.
