The product of this combustion passes put into K,
through the cross cuts, J. The air entering through the holes, H L, of
the outer china cup passes along the inner of the two concentric
cylinders, which is heated to redness, and rises highly heated toward
the upper annular burner, where the gas burns at _a_, _a_, _a_, in small
separate flames, each entirely surrounded by the hot air. This insures
perfect combustion of the gas within the basket of magnesia placed
above, and which is thus brought to a state of incandescence. It will
be seen from this description how simple and practical the
arrangement is. It is claimed for the light produced that it will
stand comparison with the electric light. Like that, it shows colors
perfectly true, and will enable an observer to distinguish between the
most delicate shades, allowing of the finest work being executed as by
daylight. It is, moreover, stated to be perfectly steady. As the
Clamond burner can be fixed to any gas bracket or lamp now in use, its
adoption causes no other expense than the cost of the burner itself.
There is no expensive installation, and when used in combination with
the electric light, it is claimed that a uniform lighting will be
obtainable instead of the unpleasant contrast between gas and
electricity. Another important advantage obtained by the Clamond
burner is the saving effected in the consumption of gas as compared
with the same power of light obtained from ordinary burners.
