I may add, they are very curious to behold, and I recommend all
visitors to the Exhibition to examine them.--_Frank Geraldy, in La

THE ARC ELECTRIC LIGHT.[1]

[Footnote 1: A recent address before the New York Electric Light
Association.]

BY LEO DAFT.


I shall experience one difficulty in addressing you this evening,
which is, that although I do not wish to take up your time with purely
elementary matter, I wish to make the subject clear to those who may
not be familiar with its earlier struggles.

If we begin at the beginning we have to go back to the time when
Faraday made the discovery that light could be produced by the
separation of two carbon rods conducting a current of considerable
tension. That is the historical point when electric lighting first
loomed up as a giant possibility of the near future. This occurred
about the year 1846. In some experiments he found that although the
circuit could not be interrupted by any considerable interval when
