It has been suggested by Dr. FRANKLIN, that the flame of two candles joined, gives a much stronger light than both of them separately. The same, has been observed by Mr. WARREN, to be the case with flames of gas-lights, which, when combined, give a much stronger light than they would afford, when in a separate state.
