Chemical, 9ft. long, slightly oval, 4ft. greatest diameter, 3/8 inch plates, 2 lbs. pressure. Although not at work, it is supposed that a gas was gently passing off through a small pipe, 30ft. long, to a receiver which was under repair, and that this gas being accidentally lighted, communicated through the pipe with that in the boiler and exploded it. One end was blown off, the rupture passing completely round through the solid plate. _No. 57. Newcastle. (Fig. 33.) November 5th. none injured._ [Illustration: _Fig. 33._] Cornish, 25ft. long, about 6ft. diameter. Tube 3ft. 6in. diameter, 3/8 inch plates, 30 lbs. pressure. Tube collapsed from overheating through shortness of water. _No. 58. Gravesend. (Fig. 34.) November 8th. 2 killed._ [Illustration: _Fig. 34._] One of two. Marine, 16ft. 6in. long, 8ft. 4in. diameter. Tube of irregular shape, about 2ft. 10in. high, 3/8 inch plates, 27 lbs. pressure. The gauge was so much out of order, that it only showed 24 lbs. under a real pressure of 80 lbs. The safety valve was defective and overloaded, and the pressure was sufficient to collapse and rupture the side flue, and the contents rushed out at the front. _No. 59. Bilston. (Fig. 35.) November 12th. none injured._ [Illustration: _Fig. 35._] One of four. Cornish, about 20 years old, 26ft. long, 6ft. 6in. diameter, 7/16 inch plates, 40 lbs. pressure. Tube 3ft. 9in. diameter had been made in two parts, joined in the centre by a narrow plate 3/8 inch thick, and it collapsed at this joint, so that the top met the bottom, and thus so retarded the issue of the contents after being set in motion, that a shock was produced, which blew out an end and half the tube in opposite directions. The shell was left resting in its seat, and little damage was done to premises. The tube had much the appearance of collapse from shortness of water, but the most probable cause was that it was too weak without strengthening hoops to bear the ordinary pressure with safety. _No. 60. Diss. (Fig. 36.) November 11th. 2 killed._ [Illustration: _Fig. 36._] Portable, multitubular, about 10 years old, 8ft. 3in. long, 2ft. 7in. diameter, 3/8 inch plates, 30 lbs. pressure. The bottom of the smoke box was reduced by external corrosion to less than 1/16 inch in thickness, and was consequently unable to bear the ordinary pressure, and a piece was blown out, and the reaction of issuing contents displaced the boiler a little and much damaged the premises. _No. 61. Rotherham. November 18th. 1 killed._ The screws of a manhole were loosened while the pressure remained in the boiler, and the lid was blown off. _No. 62. Newcastle. November 25th. 1 killed._
