This is a copy of a portion of the telegraph which was the outcome of experiments made by Baron P L Shilling between 1825 and 1830. The basis for Schilling's telegraph was the discovery by Hans Oersted of the relationship between a coil and a magnetised needle. The direction of the current running through the coil affects the direction in which the needle will swing. The receiver incorporates a disc showing white on one side and black on the other, which were used in combinations to show different letters.
