none injured.
Boiler, with two internal furnaces, 9ft. 6in. long, and 2ft. 11in. diameter, 3/8 inch plates, uniting into one tube beyond. The furnace crown collapsed near the front of the boiler.
There was an extra weight upon the safety valve, and the steam valve was left closed, so that more pressure accumulated than the boiler could bear.
No.41. Oxford.

3 injured.
Rag Boiler, not used for the generation of steam. It was a plain cylinder, with hemispherical ends, about 16ft. long, and 7ft. diameter. There was a neck at each end upon which the boiler revolved, and through one of these the steam was admitted to a pressure of 30 lbs., in order to assist in cleaning the rags. There was a large manhole for filling and emptying.
The boiler rent in the middle, and each half was blown to some distance.
The manhole was so large, that the strength of the boiler was too much reduced, and the constant strain of revolving caused a central seam to give way at the ordinary pressure.
The sketch to [No.63] is of a similar boiler.
