But by this time he had secured in his wife a rarely qualified assistant. The ultra-violet spectrum of the white stars of which Vega was taken as the type was thus shown to be a very remarkable one. A group of broad dark lines intersected it, arranged at intervals diminishing regularly upward, and falling into a rhythmical succession with the visible hydrogen lines.
We recruit more drum-majors than prime ministers from among these people. They often suffer much from torturing boring headaches, and a consequent despondency and feeling of hopelessness which colors gray the entire spiritual spectrum. Up to a certain point these sufferers have a remarkable alertness and capacity.
A substance, for example, recently discovered by President Morton, and named by him Thallene, produces a very striking elongation of the spectrum, the new light generated being of peculiar brilliancy. Fluor spar, and some other substances, when raised to a temperature still under redness, emit light.
She said that everything had colour in her thought; the months of the year ran through all the tints of the spectrum, the days of the week were arrayed as Solomon in his glory, morning was golden, noon orange, evening crystal blue, and night violet. Every idea came to her mind robed in its own especial hue.
This insight into the relation of the central colour of the continuous spectrum to its other colours still further strengthened Goethe's conviction that in the way man experiences nature in his soul, objective laws of nature come to expression.
A convenient place was selected on the Virginia side of the Potomac; a space of ten acres was carefully levelled and covered with a polished floor, rows of columns one hundred feet apart were run across it in every direction, and these were decorated with electric lights, displaying every color of the spectrum. Unsurpassed Fireworks.
With the exception of the Orangutan, the Siamang, the Tarsius spectrum, and the Galeopithecus, all the Malayan genera of Quadrumana are represented in India by closely allied species, although, owing to the limited range of most of these animals, so few are absolutely identical.
Sir William and Lady Huggins, moreover, obtained about the same time a photograph purely solar in character. The spectrum it represented was crossed by numerous Fraunhofer lines, and by no others. It was, then, presumably composed entirely of reflected light.
Thus the kind of metals which formed the sparking points could be determined by analysing the light of the spark. This suggestion has been of great service in spectrum analysis, and as applied by Bunsen, Kirchoff, and others, has led to the discovery of several new elements, such as rubidium and thallium, as well as increasing our knowledge of the heavenly bodies.
But though the blue, violet, and ultra-violet rays can act thus upon certain substances, the fact is hardly sufficient to entitle them to the name of 'chemical rays, which is usually applied to distinguish them from the other constituents of the spectrum.
