On the Long Spectrum of Electric Light. Received June 19, - Read June 19, 1862.

(London, Taylor and Francis, 1863). 4to. No wrappers as extracted from "Philosophical Transactions" 1862 - Vol. 152 Part II. Pp. 599-619 textillustrations. Clean and fine.

Fisr printing of Stoke's paper in which he investigates the spark spectra of metals, spectra of the electric arc, form and effets of the electrodes.
"By 1862 Stokes was using the spark from an induction coil to generate the spectra of various metals employed as electrodes. The invisible rays of the spectra were then examined and recorded systematically by means of flourencence, although Stokes knes that photography was already beginning to replace fluorescence as a tool for mapping out spectra."(DSB XIII, p. 77).
