And, trembling on their myriad viewless wings, Of that dim nebula just lifting now Is of a clearer blackness than is wont, * "Even to the naked eye, the stars appear of palpably different colors; but when viewed with a prismatic glass, they may be very accurately classed into the red, the yellow, the brilliant white, the dull white and the anomalous. This is true also of the planets, which shine by reflected light, and of course the difference of color must be supposed to arise from their different powers to absorb and reflect the rays of the sun.
