Fifty-five glass lantern slides document helium experiments that took place in Department of Physics in the 1920s. They originally belonged to Prof. Joseph O. Wilhelm, lecturer and co-author with J.C. McLennan of various articles. The slides were used to illustrate these articles and may also have been used for teaching. Includes original spectrographic data for the Raman Effect, views of scientific laboratory equipment, mostly likely the helium laboratory, as well as line drawings of the Helium Liquefier and the Oxygen Apparatus.
