Discovers New Explosive.

New York Times 100 years ago today, May 4, 1913:
French Professor Produces Force from Liquid Gas.
By Marconi Transatlantic Wireless Telegraph to The New York Times.
    PARIS, May 3.— Important results are expected of the remarkable discovery by Prof. Darsonville of the College de France of a new explosive, ten times more powerful than dynamite, which has just been made public at Leraure.
    It gets its force from, the liquefaction of gases. Darsonvillite, as it probably will be called, consists simply of a mixture of lampblack and liquid gas. Experiments made with it in quarries near Paris are said to have given perfectly satisfactory results.
