Pàgina 53 - It is not unconditional." 1 July does not cause August, though it invariably precedes it. For the sequence is conditioned by the coexistence of a given ratio between the solar gravitation and the earth's tangential momentum, with a given inclination of the earth's axis of rotation to the plane of its orbit. Vary either of these factors, which are the real causes of the seasons, and the hitherto invariable sequence between July and August will be altered.
Pàgina 4 - a general view of the crystal, the sixfaced tetrahedron [Fig. 20], supposed to be three-fourths covered by water attracted towards the centre of gravity of the figure, represents generally all the continents and oceans on the globe in their actual relative positions. As there are four acute solid angles on the crystal, so there are four and only four continents or masses in relief on the globe, and as there are four obtuse angles on the crystal, so there are four and only four grand depressions or...
Pàgina 52 - There is no doubt that the solid parts of the earth's crust, beneath the Pacific Ocean must be denser than in the corresponding parts on the opposite side, otherwise the ocean would flow away to the other parts of the earth.
Pàgina 36 - LATITUDE arises principally from the northern and southern parts of the lunar globe coming alternately into view in consequence of the inclination of the plane of the moon's orbit to that of the ecliptic.
Pàgina 29 - The planes of the equator and of the orbit of the moon, and the plane passing through its centre parallel to the ecliptic, have always very nearly the same intersection; the secular motions of the ecliptic neither alter the coincidence of the nodes of these three planes, nor their mean inclination, which the attraction of the earth constantly maintains the same...
Pàgina 16 - The ancient geometricians made a great many geometrical speculations respecting these bodies ; and they form almost the whole subject of the last books of Euclid's Elements. They were suggested to the ancients by their believing that these bodies were endowed with mysterious properties, on which the explanation of the most secret phenomena of nature depended.
Pàgina 45 - ... the eye, yet are so full of veins to the centre, that no art or labor can polish them. A good diamond should never contain small spots of a white or gray color of a nebulous form ; it should be free from small reddish and brownish grains, that sometimes occur on their surface, or in their interior. A good diamond should split readily in the direction of the cleavage ; it sometimes happens, however, that the folia are curved, as is the case in twin crystals. When this happens, the stone does not...
Pàgina 28 - The moon rotates on its axis in exactly the same time as it takes to go from new moon to new moon; so it always keeps the same side to the earth.
Pàgina 53 - We would observe that the making the axes of three arcs equal to each other amounts to assuming that the mean form of the earth is an ellipsoid of revolution, an assumption which has heen made by every other investigation in this subject.
Pàgina 29 - ... that their primitive difference was but small, and then the attraction of the earth would establish the equality which at present subsists.
