Prof. Trowbridge's Experiments.

The results of Professor Trowbridge's most recent experiments with his powerful new battery are of great scientific interest. He has found that if you inclose a straight wire in a glass tube and exhaust the air within, and then send a discharge of high electromotive force through the wire, the whole space of the tube will be brilliantly luminous. It looks as if the effect of the x-rays were produced from every point of the wire although it was formerly supposed that a discharge was necessary to produce this effect. The new ray, however, could probably not be used for the same purposes in taking photographs.
