A SUBMARINE ELECTRIC LAMP.

An interesting experiment was made recently at Greenock on the Tilly, a small steamer built on the Clyde for the Batavian fisheries. The ship has been fitted with a powerful electric arc-lamp of 15,000 candle power, which can be lowered into the sea, and is intended to be used in the fisheries for attracting the fish to the nets. Flexible conductors convey the current to the lamp, which can be raised or lowered by davits and pulleys from the ship's side. The lamp is inclosed in a flint-glass cylinder nine and one-half inches in diameter by fourteen and one-half inches long, and is protected by a copper grating. At the trial on the Clyde, the lamp was submerged for four hours while lighted, and the appearance of the illuminated water was very beautiful.
