This deduction from theory appeared in his recent presidential address before the British Association for the Advancement of Science, in which Professor Eddington remarked: "Probably the greatest need of stellar astronomy at the present day, in order to make sure that our theoretical deductions are starting on the right lines, is some means of measuring the apparent angular diameter of stars."
Scattered over the sward like deer in a pack the beasts grazed placidly in twos or threes, or in great bands. Without haste, almost imperceptibly, they drew aside to allow the safari to pass, and closed in again behind it. Thus the travellers were always the centre of a little moving oasis of clear space five hundred yards in diameter.
West of the large kiva there were two others, less than 20 feet in diameter. One of these was circular; the other was irregular in shape, perhaps more nearly approaching an oval form. At no fewer than five places within the ruin there are comparatively recent Navaho burials.
Upon careful examination and measurement I discovered that the diameter of the basin thus formed is to the height of the tower, as the inclination of pavement constituting the floor of the basin is to the amount of inclination of the tower.
Near an upright mass of rock over seventy feet high, and about fifty yards in diameter, which dwarfed the gigantic sycamore close to it, we made our camp, after five hours and thirty minutes' continuous and rapid marching. The people were very hungry; they had eaten every scrap of meat, and every grain they possessed, twenty hours before, and there was no immediate prospect of food.
The grippers hold the sheet securely, so that the thinnest newspaper can be printed without waste. The ink is contained in a fountain placed beneath the main cylinder, and is conveyed by means of distributing rollers to the distributing surface on the main cylinder. This surface being lower or less in diameter than the form of types, passes by the impression cylinders without touching them.
The sun was setting before he reached the wallow. His jaws hung open a little. His great head drooped lower. He had lost a great deal of blood. He was tired, and his shoulder hurt him so badly that he wanted to tear with his teeth at the strange fire that was consuming it. The clay wallow was twenty or thirty feet in diameter, and hollowed into a little shallow pool in the centre.
In regard to diameter, those of Ailsa measure nine feet, and those of Morven an inch or less. In a horizontal bed or sheet of trap the columns are vertical; in a vertical dike they are horizontal.
After some discussion, the projectile, called the Annihilator, from the fact that it annihilated space, was begun. It was two hundred feet long, ten feet in diameter in the middle, and shaped like a cigar. It consisted of a double shell of strong metal, with a non-conducting gas between the two sides.
Had it been known, as it is now, that that distance exceeds ninety million miles, or that the diameter of the orbit is more than one hundred and eighty million, that argument would doubtless have had very great weight. In reply to Tycho, it was said that, since the parallax of a body diminishes as its distance increases, a star may be so far off that its parallax may be imperceptible.
