This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1873 edition. Excerpt: ...shown, or each prism may be attached to a radial bar acting on a central pin, as shown in Fig 34. In the first place, then, what does the spectroscope tell us with regard to the radiation from the sun and the stars? And here I ask you to neglect and banish from your minds for a time any idea of those dark lines in the solar spectrum that I drew your attention to on a former occasion. I hope I shall-be able to explain them satisfactorily to you afterwards, but for the present I wish you merely to take the fact that our sun, but for the dark lines, would give us a continuous Fig. 34.--Automatic arrangement for securing the minimum deviation of the observed ray. spectrum. The spectrum of the stars is very much like-the spectrum of the sun. In Fig. 35 is seen a representation of the spectra of two stars, a Orionis and Aldebaran, mapped with the minutest care by Dr. Miller and Mr. Huggins. In both cases we should have a continuous spectrum but for the presence of the dark lines. I think you will see in a moment what I am driving at. Suppose the sun or stars composed of only sodium vapour, for instance, it is clear that their light analysed by the prism would give us no great indication of a continuous spectrum, we should merely get one bright line in the orange. But neglect the dark lines for a moment: dealing merely with the continuous spectrum of the sun and star, it shows that we have a something, whether it be solid or liquid, or whether it be a dense gas or vapour, competent to give us a continuous spectrum. So we are justified in assuming that sunlight and starlight proceed from the incandescence of a solid, liquid, or dense gas or vapour. Again, suppose that instead of looking at the sun or the stars we observe the moon, as Fraunhofer...
