On the spectra of ignited gases and vapours, with especial regard to the different spectra of the same elementary gaseous substance
In order to obtain the spectra of the elementary bodies, we may employ either flame or the electric current. The former is the more easily managed, but its temperature is for the most part too low to volatilize the body to be examined, or, if it be volatilized or already in the state of gas, to exhibit its characteristic lines. In most cases it is only the electric current that is fitted to produce these lines; and the current furnished by a powerful induction coil was what the authors generally employed.
