ELECTRICAL TELEGRAPH. Professor Wheatstone, the inventor of the electrical telegraph which is now at work on the Great Western railway, is at present in Brussels, where he has been trying the new improvements he has introduced in his apparatus. Mr. Wheatstone has succeeded in so simplifying his apparatus that he has reduced the number of wires employed to two. The great objection which had been previously made to the telegraphs was the difficulty of repairing the wires in case any should be broken or damaged, as it was supposed it would not be possible to tell where the fracture was.

This difficulty has now been obviated by means of a small carriage moved along the line of the telegraph. The place where the defect lies is indicated by a magnetic needle, which changes its position the instant it arrives at the part where the connection is broken. Professor Wheatstone conceives that it is possible to communicate with his apparatus between Dover and Calais. He has been repeating his experiments at the Brussels' Observatory in the presence of many scientific men. Inventor's Advocate.
