Those shown in [Fig. 21] and [Fig. 22], [No. 23, 1870], and [No. 53, 1869], were from the collapse of the central tubes, which were weakened by external and internal corrosion respectively. In [Fig. 24], [No. 35, 1868], the shell was in bad order from over work and receiving too much heat from four large furnaces, one of these especially causing a constant mass of flame to impinge upon a single plate, which resulted in a seam rip.
