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.
