APPLICATIONS OF THE ELECTRIC LIGHT. 279 



at Rheims; the workshops of Coron and Vignat, at Saint- 

 Etienne; of Maes, at Clichy; of Descat-Leleu, at Lille; of 

 Pulher and Sons, at Pesth; of Carel, at Ghent; the yards of 

 Jeanne Deslandes, at Havre; the workshops of Mignon, 

 Ronart, and Delinieres at Montluc,on; the quay of the canal 

 between the Marne and the Rhine, at Sermaize; the goods 

 station at La Chapelle, Paris; and also the different places 

 undertaken by the Jablochkoff Company mentioned in 

 pages 228-9.* The result has everywhere been satisfactory. 

 Fontaine's work gives details on the fitting up of these 

 systems of lighting. We shall here merely describe that of 

 the station of the Chemin du fer du Nord, on account of the 

 ingenious method by which a light is obtained not fatiguing 

 to the eye, and capable of illuminating the various parts of 

 the hall by nearly perpendicular rays, thus obviating the 

 shadows thrown by packages, and throwing over them a 

 flood of light like that of the torrid zone. 



This method consists in arranging round the regulators, 

 which are hung up at various points of the halls, a kind of 

 reflector partly formed by the support of the lamp and partly 

 by a sort of inverted ground-glass funnel, so placed that the 

 luminous arc cannot be seen directly from any part of the 

 hall. The light thus partially stopped is reflected towards 

 the ceiling, as well as that which proceeds from the upper 

 part of the arc; and as the ceiling is painted white, it is 

 capable of forming in its turn an immense reflector, which 

 sends down the luminous rays almost vertically, and thus 



* Besides these establishments, Fontaine mentioned, in the beginning of 

 1877, a number of other workshops lighted in this way. Among the rest 

 were the cannon foundry at Bourges ; the workshops of Cail, those of the 

 Mediterranean Iron Works Co. at Havre, those of Crespin and Marieau at 

 Paris, of Beaudet at Argenteuil, Thomas and Powell at Rouen, Ackermann 

 at Stockholm, Avondo at Milan, Quillacq at Anzin ; those of Fives-Lille, of 

 Tarbes, of Barcelona ; the Midi Stations at Brussels ; the workshops at 

 Fourchambault ; the foundries of Besseges and of Fumel ; the dye-works ot 

 Guaydet at Roubaix, of Hannart at Wasquehal ; the weaving shop . ot 

 Baudot at Bar-le-Duc ; the laundry of the Lyons hospitals, &c.
