But incomparably smaller amounts still are really suffi-cient to distinguish each element. And yet a grain whenmeasured out in water is only one drop ! Does not the study ofcolors, then, open up a science to man, magnificent in its revela-tions of the minute, and minute in its revelations of the mag-nificent, taking the sun and stars to pieces on the one hand, andpiercing far clown towards the realm of atoms on the other ? Butnot only does it reveal the potencies of matter, but ascends tothe still grander empire of the soul, as we shall see hereafter inChromo-Mentalism. II. The Spectroscope. 1. In order to reduce these spectra of different substances toabsolute system, with scales of measurement so that by com-parison the lines of the different substances can be determined,an instrument called the Spectroscope (fog. 166), has been Fig. 166. The Spectroscope The figure represents one of the best forms of the instrumentas made by Steinheil of Munich. P, is a prism fixed upon thecentral iron stand. A, is a tube with a lens in the end near theprism, while the other extremity has a fine vertical slit for the METALS DISCOVERED PA THE SPECTROSCOPE. 219 admission of light. The width of this slit is regulated by thescrew e. The stand E supports a Bunsens burner, or sometimesa common gas burner in the flame of which the substance to beanalyzed is held by a sliding rod which moves up and down onthe stand s. This burner is placed opposite the upper half ofthe slit and sends its light directly clown the tube to the prismP. On the other s
