Some rents took place at the under side of the shell, allowing the central portion to open out and blow away. The portion containing the dome was thrown to the left, and the other to the right. The front end, with 3 rings of the shell, with the tubes and back end, were but little moved from their original position. The tubes were dented in on the top and bottom, by the fall of some large coping stones upon them, but the crowns of the furnaces were uninjured, and there was no sign of shortness of water or overheating. Extensive corrosion on the under side of the shell, where it rested on the brickwork, had so reduced the strength, that it was unable to bear the working pressure. In the sketch the fragments are drawn so as to show their position when in the boiler. _No. 51. Newark. September 21st. none injured._ One tube Cornish. The tube collapsed from shortness of water, and the escape of the steam and water blew off the door frame. _No. 52. Ashton. September 23rd. 1 injured._ Plain Cylindrical Boiler, 7ft. long, and 2ft. diameter, 3/8 inch plates, 30 lbs. The upper part of the boiler at the first ring of plates was torn off, and the front end was blown out. Extensive external corrosion, where the plates rested against the brickwork, rendered the boiler too weak to bear the ordinary pressure. _No. 53. Norwich. (Fig. 23.) September 25th. 7 killed._ [Illustration: _Fig. 23._] One Tube Cornish, 20ft. long, 4ft. 6in. diameter, tube 2ft. 6in. diameter, 3/8 inch plates, 100 lbs. It was double-rivetted, and the crown of tube was strengthened with angle iron. The shell was formed of six rings, each of two plates alternately jointed top and sides. The third ring from the front had stripped off, and was thrown to the right and forwards against a wall. The line of rent was confined to the plates forming the ring, which was an outer one, and covered the two adjoining rings in the laps, the rent being from the edge of the inner lap to the nearest rivets. The first rent had taken place in the solid iron, about 1 inch from the rivets of a seam on one side, and from this the rent had extended along the seams on either side, and of course the whole ring soon tore off when the equilibrium was destroyed by the first rent. The fittings of the boiler were sufficient, except that there was only one safety valve, and that was so constructed that it could only open a very little way. The cause was a defect in the iron at the point of the first rent, and accumulated pressure during the time of standing. _No. 54. Macclesfield. September 25th. none injured._ Multitubular Boiler, with large internal fireplace, 60 lbs. The furnace crown became overheated from shortness of water, and was crushed down and torn across two seams. The boiler was lifted from its seat and thrown back against a stone wall. _No. 55. Chelmsford. October 5th. 1 killed, 7 injured._
