I presently learned to my surprise and amusement that the amiable confederate of the conjurer was no other than the physicist Kirchoff, then in fresh and brilliant fame as the inventor of the spectroscope and the initiator of the scientific method known as spectrolysis.
Thus the kind of metals which formed the sparking points could be determined by analysing the light of the spark. This suggestion has been of great service in spectrum analysis, and as applied by Bunsen, Kirchoff, and others, has led to the discovery of several new elements, such as rubidium and thallium, as well as increasing our knowledge of the heavenly bodies.

The wonderful discovery of spectrum analysis by Kirchoff and Bunsen in 1861 has shown that the whole stellar universe is made up of the same chemical materials as those with which we are familiar upon the earth.
"Don't you think it is strange that alongside the greatest achievements of science, alongside Galileo, Kepler, Laplace; alongside the spectrum analysis and the law of the conservation of energy; alongside Kirchoff and Bunsen; alongside steam, gas, electricity, the blindest and most antiquated superstitions still survive, powerful as ever?
In those days the name of Kirchoff was coupled always with that of an associate, the chemist Bunsen, when there was mention of spectrum-analysis; and in my time at Heidelberg, Bunsen was at hand and I became as familiar with his figure as with Kirchoff.
He was in the front rank of the chemists of all time, and I suppose had equal merit with Kirchoff in the momentous discovery in which their names are linked. There was, however, at this time in Heidelberg a scientist probably of greater prestige than even these, whose contemporary influence was more dominant, and whose repute is now, and likely to be hereafter more prevailing.
He tried this with the annular eclipse of 1836, with a negative result which has never been accounted for, and which seemed to condemn Brewster's view. In 1859 Kirchoff, on repeating Frauenhofer's experiment, found that, if a spirit lamp with salt in the flame were placed in the path of the light, the black D line is intensified.
The discoveries of Grimaldi and of Fresnel in regard to interferences, those of Faraday, of Arago, of Foucault, of Fraunhofer, of Kirchoff, and of hundreds of others owed something to "fortune." It is said that the sight of a crab suggested to Watt the idea of an ingenious machine.
[The explanation of the solar spots above suggested, which was originally propounded in opposition to that of M. Faye, was eventually adopted by him in place of his own. In the Comptes Rendus for 1867, Vol. LXIV., p. 404, he refers to the article in the Reader, partly reproduced above, and speaks of me as having been replied to in a previous note. Again in the Comptes Rendus for 1872, Vol. LXXV., p. 1664, he recognizes the inadequacy of his hypothesis, saying: "Il est certain que l'objection de M. Spencer, reproduit et développée par M. Kirchoff, est fondée jusqu'
