The electro-magnetic clock of Professor Wheatstone is another of those singular inventions, and one which, though it may be less useful, is certainly not less ingenious and surprising than his telegraph. The object of the inventor was to enable a single clock to indicate exactly the same time in as many different places, distant from each other, as may be required. A standard clock in an observatory, for example, would thus keep in order another...
