PROF. ROENTGEN.

Something of the Personality of the Famous Scientist. The name of Prof. Roentgen has become world-famous within the past few weeks. Everybody is talking of his wonderful discovery of the X ray. Scientists and would-be scientists everywhere are experimenting with vacuum tubes and X rays. Yet with

it all little is known in this country of their discoverer’s personality. William Conrad Roentgen is of Dutch birth. He studied at Zurich with the famous scientist Kundt,' whose assistant he became. In the relation of professor and assistant Kundt and Roentgen went from Zurich to Wurzburg, and thence to Strasburg. Roentgen became professor of mathematics at the Agricultural College of Hohenheim in 1875. In 1879 he became a professor In the University Institute of Physics in Giessen. He returned to Wurzburg in 1888 and has been teaching there ever since. He has published several valuable scientific works, including a treatise on the use of the ice calorimeter to determine the intensity of sunlight, and another on a method to fix the isothermal surface of crystals. He has long been engaged in electrical research, and made a special study of the figures produced in dust by electrical discharges, and the phenomena shown by electricity In passing through various gases. He has delved into nearly every branch of physips. He invented an aneroid barometer to tell the weight of the atmosphere; he has also published a treatise on the theory and working of the telephone.—New York Evening Sun.
