The Spheroidal State of Water

Abstract

I HAD the pleasure a few days ago of visiting Messrs. Johnson's celebrated iron wire manufactory in Manchester. There may be seen a series of furnaces and rolling mills which in twenty-four hours can convert a truck load of the best Swedish iron into the bright and polished galvanised wire which is now being so extensively employed to complete our very perfect system of Post Office telegraphs. Every stage of the process passes beneath the eye of the observer; the melting of the pigs, the formation of the billets, the puddling of the bloom, the shingling of the balls, the rolling of the bars, and their subsequent extension by further rolling, and drawing into telegraph wire.
