“NEWTONIAN” LAMPS
FOE BURNING CRYSTAL OR ANY MINERAL OIL,
THE MOST POWERFUL AND SIMPLE LAMP YET CONSTRUCTED. This Lamp has for many years occupied the premier position among oil lamps for lanterns, and still exceeds in brilliancy and penetrating power any lamp in the market.

Every lamp is carefully tested and put in adjustment before being sold.
I he difficulty (so frequently experienced with lamps of a high illuminating power) of making the flames draw up readily, owing to the sharp draught, is entirely obviated by the peculiar construction of the chimney. If the lamp is lit and burnt for two minutes using only the lower part of the chimney, as in Fig. 8075, the upper portion may be then fitted into its place on the top, and the flames will at once be entirely under control.
For many years Newton’s Patent 1 1 Refulgent ’ ’ Lamps held the first place for illuminating power; the light given by the ‘'Newtonian” Lamp is, however, considerably more intense Board°c&c Ul" ** ^ ^ adopted as the pattern ly the War Department, the School
