z, 500, 900 candles by means of four tense,
instead of twenty-four, as previously,
and by a novel system of rotation make
the ''aash" every twenty seconds. This,
the inventor claims, is the finest result

Electric light baths ore among the
latest inventions. The necessary parts
| of such a bath are a cabinet which will
