" But this apparently harmless "bang" may cause a panic in a public hall, which may lead, possibly, to fatal results. So, for the present, at any rate, I shall do without the ether light, while, at the same time I shall look forward to its gradual perfection with the greatest interest. It is only fair to state that this light is much used in America, its greatest champion being Mr. Ives, who recently con- tributed a paper on the subject to the Franklin Institute. Mr. Ives is such a good worker that his words carry weight with them. I quote the following remarks from his paper : — " Notwithstanding the great success of this means for producing the limelight, and the important advantages which it offers, I have always recognised in it certain minor faults, which I hoped to overcome in course of time, and my object in preparing this paper has been to call attention to some recent improvements I have made, which I believe will greatly extend the use of the light, and increase its popularity.

The second is in the use of petroleum ether (rhigolene), which gives the same light as sulphuric ether, but vaporises at a lower temperature, costs much less, and contains neither alcohol nor water to accu- mulate in the saturator.
