Page 5 - D stands before the slit in such a position that the mouth of the flame is in a straight line with the axis of the telescope B. Somewhat lower than the point at which the axis of the tube produced meets the mouth, the end of a fine platinum wire bent round to a hook is placed in the flame. The platinum wire is supported in this position by a small holder, E, and on to the hook is melted a globule of the metal or salt of the metal which it is desirable to examine.

Each particular portion of the spectrum thus corresponds to a certain point on the scale. If the luminosity of the...
