Page 198 - A monstrous eft was of old the Lord and Master of Earth, For him did his high sun flame, and his river billowing ran, And he felt himself in his force to be Nature's crowning race. As nine months go to the shaping an infant ripe for his birth, So many a million of ages have gone to the making of man : He now is first, but is he the last ? is he not too base ? VII.
Page 348 - Race after race, man after man, Have thought that my secret was theirs, Have dream'd that I lived but for them, That they were my glory and joy. — They are dust, they are changed, they are gone ! I remain.
Page 38 - ... according to their substance they take more or less time in cooling. It is evident from the increase of heat as we descend into the earth that the earth is cooling, and we know by experiment, within certain wide limits, the rate at which its substances, the matters of which it is constituted, are found to cool. It follows that we can approximately calculate how hot it was so many million years ago. But if at any time it was hotter at the surface by 50° F.
Page 56 - As a centre stood the full and intensely black disc of the moon, surrounded by an aureola of soft bright light, through which shot out, as if from the circumference of the moon, straight massive silvery rays, seeming distinct and separate from each other, to a distance of two or three diameters of the lunar disc ; the whole spectacle showing as upon a background of diffused rose-coloured light...
Page 146 - TJiefucl value of food. — Heat and muscular power are forms of force or energy. The energy is developed as the food is consumed in the body. The unit commonly used in this measurement is the calorie, the amount of heat which would raise the temperature- of a pound of water 4° F.
Page 56 - This light was most intense and extended furthest at about the center of the lower limb, the position of the southern prominence. The silvery rays were longest and most prominent at four points of the circumference, two upon the upper and two upon the lower portion, apparently equidistant from each other, and at about the junctions of the quadrants, designated as " limbs,'' giving the spectacle a quadrilateral shape.
Page 35 - At the present time we can only say that the nebular hypothesis is indicated by the general tendencies of the laws of nature, that it has not been proved to be inconsistent with any fact, that it is almost a necessary consequence of the only theory by which we can account for the origin and conservation of the sun's heat, but that it rests on the assumption that this conservation is to be explained by the laws of nature as we now see them in operation. Should any one be...
Page 76 - In those years in which they occur most frequently, it is found that the ordinary oscillations of the magnetic needle are more extensive than usual. Now when these peculiarities had been noticed for many years, it was found that there was an alternate and systematic increase and diminution in the intensity of magnetic action, and that the period of the variation was about eleven years. But at the same time, a diligent observer had been recording the appearance of the sun's face from day to day and...
Page 316 - Self is the Lord of all things, Self is the King of all things. As all the spokes of a wheel are contained in the nave and the circumference, all things are contained in this Self; all selves are contained in this Self. Brahman itself is but Self V This Atman also grew ; but it grew, as it were, without attributes.
Page 28 - ... of degrees, if this quantity of heat could ever have been present in the sun at one time. This cannot be assumed, for such an increase of temperature would offer the greatest hindrance to condensation. It is probable rather that a great part of this heat, which was produced by condensation, began to radiate into space before this condensation was complete. But the heat which the sun could have previously developed by its condensation, would have been sufficient to cover its present expenditure...
