oxycalcium light
(gcide) | Drummond light \Drum"mond light`\ [From Thomas Drummond, a
British naval officer.]
A very intense light, produced by turning two streams of gas,
one oxygen and the other hydrogen, or coal gas, in a state of
ignition, upon a ball of lime; or a stream of oxygen gas
through a flame of alcohol upon a ball or disk of lime; --
called also oxycalcium light, or lime light.

Note: The name is also applied sometimes to a heliostat,
invented by Drummond, for rendering visible a distant
point, as in geodetic surveying, by reflecting upon it
a beam of light from the sun.
