THE SIEMENS FURNACE. THERE is a small collection of gas-furnace models exhibited at Paris by Mr. Siemens, and now distinguished with the highest prize of the international jury, namely, the " grand ; It may be said with justice that the Siemens furnace in this present Exhi- bition holds much the same position which the Bessemer process held in 1862, namely, that of the most important and most success- ful metallurgic invention of the day. It is hardly less important; than the Bessemer process, and, although its invention dates about * as far back as Mr. Bessemer's patents, it has only lately attained commercial success. In the space of the last five years che Sie- mens furnace has not been very materially altered or improved, but it has been largely introduced and its success established in many different branches of industry. The first manufacturers in England who availed themselves of the new furnace were the glass-makers. For purposes of metallurgy, greater difficulties and prejudices required to be surmounted. Some of the steel-makers on the Continent led the way. Mr. Mayr, of Leoben, in Styria, we understand to have been the first to introduce the new furnace for crucible steel-making on a large scale. In this instance the unfavorable position of the Styrian iron works, with regard to the supply of mineral fuel, was the principal inducement to apply gas in the steel-melting furnace. The gas is made,'at Mr. Mayr's works, from lignite, which cannot be directly applied for melting steel, as the heat from it, when burnt on the grate, is not sufficient to produce the high temperature required for this operation. Mr. Mayr erected ten gas-furnaces, and they have proved a complete and perfect success, enabling him to make crucible cast steel by means of the ch
