inches deep, 6 feet in diameter, lined with brick, and when examined contained 7 feet 6 inches of water. It was arched in at the top, dome fashion, and tightly closed at a level 3 feet 6 inches below the street by a cover occupying the crest of the dome. The bottom of the main drain of the house No. 40 Broad Street, lay 9 feet 2 inches above the water level, and one of its sides was distant from the brick lining of the well only 2 feet 8 inches. It was constructed on the old fashioned plan of a flat bottom, 12 inches wide, with brick sides rising about 12 inches high, and covered with old stones. As this drain had but a small fall or inclination outward to the main sewer, the bottom was covered with an accumulation of soil deposit about 2 inches thick, and upon clearing this soil away the mortar joints of the old stone bottom were found to be perished, as was also all the jointing of the brick sides, which had brought the brickwork into the condition of a sieve, and through which the house drainage water must have percolated for a considerable period. [Illustration: ASIATIC CHOLERA AND THE BROAD STREET WELL. LONDON 1854.] After opening back the main drain, a cesspool, intended for a trap but misconstructed, was found in the area, 3 feet 8 inches long by 2 feet 6 inches wide and 3 feet deep, and upon or over a part of this cesspool a common open privy, without water supply, for the use of the house, was erected, the cesspool being fully charged with soil. This privy was formed across the east end of the area, and upon removing the soil the brickwork of the cesspool was found to be in the same decayed condition as the drain, and which may be better comprehended by stating that the bricks were easily lifted from their beds without the least force, so that any fluid could readily pass through the work, or as was the case when first opened, over the top course of bricks of the trap into the earth or made ground, immediately under and adjoining the end wall eastward, this surface drainage being caused by the accumulation of soil in, and the misconstruction of, the cesspool.
