J. Tram Taytor, in British Sourial of Photography, says :--‘* Messrs. Perken, Sou, and Rayment claim to have produced a triple-wick oil lamp, ia which the luminosity is equal toONE HUNDRED CANDLE POWER —while the light is very pure, and the heat less than usual. We have been.present at trials made with it, and find their allegations asto PURITY and INTENSITY OF FLAME are maintained.” ;
T. Rotas, in Photographic Work, says:—‘*The Optimus 100 Candle Power Oil Lamp-:the light certainly surprised us... The brightness—and above all the whiteness-—of the disc recalling a lime light. . .."
Amateur Photographer, Noy 10, 1893.—"' Messrs. Perken, Son, and Rayment, of 99, Hatton Garden, have just introduced a great improvement in oil-lamps, which will be warmly welcomed by all wha use this form of illuminant. From the diagram it will beseen that central as well as side air shafts are provided, and with the greater supply ot air iscombined greater illumination and greater freedom from smell. We have had an opportunity of severely testing this lamp against some of
of the best ardinary farms, and the increase in illumination is at least three times. |

useful for enlarging. _ j
By means of air shafts enormaus increase of brilliancy is secured (which has heen computed to equal three times the candle power of the refulgent lamps hitherto sold_with magic lanterns—vide Report of Meeting, Bristol Photographic Association, Feb. 24, 1$93).
