Messrs. Heaton have supplied coins to no less than 39 states or authorities. In 1868, the Italian Government ordered five million lire in pieces of 10 centimes; and in consideration of the satisfactory manner in which this and other coinages had been carried out, his majesty, King Victor Emmanuel, conferred the honour of knighthood on the firm. =Electric Lighting.=--[HENRY LEA, M.I.M.E.]--The period of fifteen years following the last Meeting of the British Association in Birmingham, in the year 1865, was devoid of any undertakings in electric lighting, other than in the direction of the application of powerful arc lights for lighthouse purposes, as practised by Messrs. Chance Bros., of Spon Lane, near Birmingham, who, beginning in 1862 with apparatus having optical adjustments for electric arc lights of small power, proceeded to introduce more and more powerful lights, of which the Souter Point revolving light of the 2nd and 3rd order built in 1870, the South Forelands fixed lights, two in number, and of the 3rd order, built in the same year; the Sydney Heads light of the 1st order and of 11,000 candle power, built in 1880; and the flashing light at Tino, near Spezia, a lamp of the 2nd order, finished in 1885, are examples shewing the great progress made during the period referred to. The Sydney Heads light is said to be the leading light of the world. The motive power employed for it is the Otto silent gas engine. The carbons are 23 millimetres, or upwards of ⅞″ in dia. Particulars of these undertakings will be found in a special paper upon Lighthouse Work in another part of this volume. The first application of arc lighting for ordinary business purposes in this district is believed to be that of the Birmingham Household Supply Association Limited, which was fixed in the year 1880-1 under the superintendence of the writer, who employed a pair of 8″ × 12″ Horizontal Tangye Engines to drive a Brush Dynamo working sixteen arc lamps. Amongst other examples of arc lighting subsequently put down may be named those at Messrs. Brown Marshalls & Co.’s Carriage Works at Saltley, Messrs. John Wilkes and Sons’ Rolling Mills in Liverpool Street, Messrs. Elkington & Co.’s Show Rooms, in Newhall Street, the New British Iron Co.’s Works at Corngreaves, the Lower Grounds at Aston Park, and Messrs. Cadbury Bros.’ Cocoa Manufactory, near Birmingham, the latter being only very recently started upon the Gulcher system.
