	(?). [From Thomas Drummond, a British naval officer.] )
Drum"mond light`

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.
