"The germs are much larger than bacteria and they can be seen with a comparatively low power microscope swiftly darting between the blood cells, brushing them aside, but not penetrating them as some parasites, like that of malaria, do. Besides, spectroscope tests show the presence of a rather well-known chemical in that blood." "A poisoning, then?" I ventured.
I should tell him of the ocean steamers, the railroads that spread themselves like cobwebs over the civilized and half-civilized portions of the earth, the telegraph and the telephone, the photograph and the spectroscope.
As far as physical conditions are concerned, there are suns similar to our own, as revealed by the spectroscope, and which have the same eruptive energy. Astronomical Science has incontrovertibly demonstrated, and evidence is continually increasing to show that dark, opaque worlds like ours exist and revolve around their primaries.
The prominences, however, although they were discovered during an eclipse, can now, with the aid of the spectroscope, be seen at any time.
You get much nearer those distant orbs when a spectroscope is placed at the end of the telescope, and the ray of light coming from sun and star is widened out into a band of color, which tells a marvelous story. That light, that has been for years, and perhaps for centuries, on its way to you, now discloses the very nature of the substances which compose those fiery globes.
When the firmament of Hebrew cosmogony has given way to interstellar spaces and the telescope and the spectroscope plumb the depths of the universe, resolving nebulæ into star drifts, faith is bound to reflect the change. The power which manifests itself in the universe becomes thereby a vaster power, operating through a vaster sweep of law.
Therefore there can be no doubt that the colours are genuine enough, and are telling us some message. This message we are able to read, for we have begun to understand the language the stars speak to us by their light since the invention of the spectroscope.
Hence arose the branch of astronomy called astronomical physics, a science which claims a large portion of the work of the telescope, spectroscope, and photography. In this new development it is more than ever essential to follow the dictum of Tycho Brahe not to make theories until all the necessary facts are obtained.
"There's only one place, I guess, after all," said Kate, "where you can be shut up with nothing but your own dust!" "Sharper than ever, Kate Sencerbox! I guess you do get rubbed up!" "Mr. Stalworth is there to-night," said Bel. "He tells as good stories as he writes. And they've been talking about Tyndall's Essays, and the spectroscope. Mrs.
But it also shows a green line corresponding with no known terrestrial element, and the name "coronium" has been given to the substance causing it. A vast number of facts have been added to our knowledge about the sun by photography and the spectroscope.
