In investigating the tesla-luminescence of cod-liver oil, it was observed that the nature of the luminescence would change very rapidly with the pressure. This effect was noticed for the cod-liver oil vapor, for carbon-dioxide and for air. In the case of air it was found that there was an abrupt change from a pinkish glow at about 4 mm. pressure to a bright orange at about 2 mm. The actual value of the pressure at which this effect took place has not as yet been accurately determined. A preliminary spectroscopic study of the luminescence has shown that bands which are prominent at the higher pressure disappear at the lower.
