In the last century, at a meeting of a society of mathematicians at Liverpool, one of the members proposed to lay a wager, that he would read a paragraph of a newspaper, at ten yards' distance, with the light of a farthing candle. The wager was laid, and the proposer, having covered the inside of a wooden dish with pieces of looking-glass, fastened in with glaziers' putty, placed his reflector behind the candle, and won his wager. One of the company marked this experiment with a philosophic eye. This was Captain Hutchinson, the dockmaster, with whom originated the reflecting lighthouses, erected at Liverpool in 1763.
