Attempts have been made to introduce the limelight, that being of far greater brilliancy than any other.  We read of a curious experiment connected with it.  A limelight was placed on the summit of a hill, called Slievesnaught, in Ireland, which was always enveloped in haze by day.  Between it and the observing station was a church tower, twelve miles distant, and on this station an ordinary reflector was fixed, while the hill itself was seventy miles distant.  Notwithstanding the great difference in the distances, the limelight was apparently much nearer and brighter than the light twelve miles off.
