Abstract
The possibility of an effect of the free electrons in a highly ionized gas on the frequency of light traversing it has been investigated. Electrons to a density of about 5× per cc were produced in a series of low voltage arcs. Light of wave-length 5461A was passed through the arcs and a frequency shift sought by means of an interferometer in vacuum. A shift of approximately two parts in could have been detected. A very satisfactory null result was obtained. This is interpreted with special reference to the possibility of explaining the nebular redshift by such a mechanism. It is concluded that the shift is not attributable to interstellar electrons.
