Once available for study under electrical excitation in vacuum tubes, helium was found to have many other lines in its spectrum, which have been identified in the spectra of solar prominences, gaseous nebulæ, and hot stars. Indeed, there is a stellar class known as helium stars, because of the dominance of this gas in their atmospheres.
The stony escarpment upon which they stood had the contour of a man's face, and it was covered with furze as with a beard. People in the field above were preserved from an accidental roll down these prominences and hollows by a hedge on the very crest, which was doing that kindly service for Elfride and her mother now.
The rapid movement of the tendons over bony surfaces and prominences would soon produce an undue amount of heat and friction unless some means existed to make the motion as easy as possible. This is supplied by sheaths which form a double lining around the tendons. The opposed surfaces are lined with synovial membrane, the secretion from which oils the sheaths in which the tendons move.
It snapped at a few ears, and moved its head slowly to choose its direction. In a couple of leaps Pelle was up to it and had hold of its tail. He hit it over the nose with his cudgel, it turned quickly away from the rye, and set off at a flying pace down toward the others, while blows rained down upon its bony prominences.
The two classes of phenomena, at any rate, stand in a most intimate relation; they obey the same law of periodicity, and are confined to the same portions of the sun's surface, while quiescent prominences may be found right up to the poles and close to the equator. The general distribution of prominences, including both genera, follows that of faculæ much more closely than that of spots.
Frankland and Lockyer communicated to the Royal Society a series of experiments on gaseous spectra under varying conditions of heat and density, leading them to the conclusion that the higher solar prominences exist in a medium of excessive tenuity, and that even at the base of the chromosphere the pressure is far below that at the earth's surface.
Lemme read your palm, and tell you." She held his hand long, then tossed it aside with petulance, parted his hair and peered into his face, passed her hands lightly over his head for the prominences, dashed unexpected tears from her eyes, and then said with decision: "There are two of you in there," tapping his chest. "I can't tell why, but I can read, or feel one man, and outside I see another."
Look at the flat, narrow haunch bones the long and narrow passage the coarse, outwardly curved, ischiatic prominences on which the Gibbon habitually rests, and which are coated by the so-called "callosities," dense patches of skin, wholly absent in the Gorilla, in the Chimpanzee, and in the Orang, as in Man!
Some of these stones bore prominences resembling the breasts of a woman. The accumulations of earth and rubbish about the NURHAGS are, some of them, from six to ten feet high.
During the eclipse, it was seen framed, as it were, in a pointed arch of coronal light, the symmetrical arrangement of which with regard to it was obviously significant. Both its unspringing shape, and the violet rays of calcium strongly emitted by it, contradicted the supposition that "white prominences" represent a downrush of refrigerated materials.
