H.M.S. Raleigh, 1874. 'The vessel is built with iron transverse frames, and with a complete iron skin-plating, half an inch thick, over all her body...The bottom is finally sheathed with copper, in the same way as a wooden vessel...The engines, by Messrs. Humphreys, are horizontal, not compound, of 800-horse power nominal, with surface condensers...There are eight tubular boilers, containing altogether 5500 brass tubes, fitted with superheaters for drying the steam. These are heated by thirty-two furnaces...The armament consists, on the main deck, of two 64-pounder chase guns and fourteen 7-in. 90-cwt. side guns...on the upper deck, two 9-in. 12 ton guns revolving on turn-tables, one firing all round the bow, the other astern; with two 64-pounder chase guns and two 64-pounder side guns. The total complement is 520, officers and men...The fire-extinguishing apparatus consists of a powerful steam-engine and two double-action pumps, having a line of 6-in. copper pipe running fore and aft the whole length of the ship, with branches to attach hose for combating a fire in any part of the vessel. The power of these pumps is sufficient to force two streams of water from 2-in. nozzles over the mainyard'. From "Illustrated London News", 1874.
