THE DRUMMOND LIGHT.

Previous

The importance of simplicity in inventions for popular use, has been shown in the late Lieutenant Drummond's apparatus for illuminating lighthouses with his oxyhydrogen light; that is, a stream of oxygen and another of hydrogen, directed upon a ball of lime. Experimentally, the light has succeeded beyond the expectation of the inventor; but the machinery or apparatus remains to be simplified before it can be worked by the keepers of lighthouses.
