This curious machine consists of a glass lanthorn about seven feet high, and six in diameter, glazed with the best plate glass; the frame of which is copper, and covered with a roof of the same metal. In the centre of the lanthorn is set upon a frame a large hexagonal reflecting cylinder, four feet in height, and three feet in diameter. This cylinder is made of copper, the outside of which is covered with cement, upon which are placed nearly 4,000 small mirrors, each mirror about an inch square. In the centre of this cylinder is fixed a reservoir of oil, which, by fixed pipes passing through hexagonal divisions of the cylinder, support and convey the oil to a large circular tube, which is placed about eighteen inches from the surface of the cylinder, and upon this tube are fixed 126 lamps. One of these lighthouses was made by an order of the elder brethren of the Trinity House, sent on board their yacht, with several of the brethren, and sailed for Lowestoft, in Suffolk, to make a trial of its utility. Accordingly in the night of the 23rd of June, a temporary scaffold being erected for that purpose, the machine was hoisted and the lamps lighted; when it was found to answer beyond conception, exhibiting a globe of fire of a steady and most vivid brightness. This experiment was made at a small distance from the lighthouse commonly made use of, the light of which is supported by a coal fire, and was exerted to the utmost on this occasion, to maintain, its superiority; and was appointed to be the criterion by which the difference was to be determined. The yacht accompanied by some boats, sailed off to sea the preceding day, so as to be out of sight of land before sunset—the time appointed for lighting it. They sailed in for the land, and discovered the new light-house as soon as the convexity of the sea would permit, it being at least twenty miles from the shore, and sailed five or six miles nearer before they could perceive the fire of the old light-house. The brethren of the Trinity House being thus convinced of the great utility of this invention, gave orders the next day to have it taken down and sent to the Island of Scilly. SECTION III.
