Page 26 - ... a part of the disk of the sun ; and that every time it is in opposition, it ought to pass through the shadow which the earth projects behind it ; so that there would be, in the former case, an eclipse of the sun, and in the latter, an eclipse of the moon.
Page 5 - In vain does ignorance demand of us how the earth can remain suspended in the air without any support. Let us look upon the heavens, and observe how many other globes roll in space. The force which supports them is unknown to us ; but we see its effects, and we investigate the laws according to which these effects take place. Let us then lay aside all uneasiness concerning the antipodes...
Page 38 - The azimuth of a body, is the arc of the horizon intercepted between the south point, and that in which a vertical circle passing through the zenith and the body, cuts the horizon. Amplitud«.
Page 166 - Pyrennees afford. ^n general a^ tne chains of mountains in the same continent, seem to have a mutual connection more or less apparent : they form a sort of frame work to the land, and appear, in the origin of things, to have determined the shape which it was to assume ; but this analogy, were we to generalise too much, would lead us into error. There are many chains, which have very little, or rather no affinity to each other. Such are the mountains of Scandinavia and of Scotland ; mountains as independent...
Page 236 - Zinc, which forms the connecting link between the ductile metals, and those which are not so, is found oxidated, and then it is commonly called calamine, or lapis calminaris. There are mines of it in Alsace, in Normandy, near Aix la Chapelle, in Brisgaw, in Carinthia, in the county of Somerset in England, and many other places.
Page 127 - ... which he can advance, either with artillery, or only with his musket; every ford in a river, every defile by which he can turn the position of an enemy; in a word, these maps should exhibit all the localities which can influence his operations; the number of good military maps is therefore very limited. It is in great part to the excellence of those supplied by the Depot de la Giierre, that the French armies owe their successes.
Page 451 - A number of -lightnings appear to flash from the midst of the burning mass. On a sudden, the brilliant cascade seems to fall back into the crater, and its fearful splendour is succeeded by profound darkness. The effervescence, however, goes on in the interior abysses...
Page 32 - To lunar observations, however, is joined the use of timekeepers, which serve in the intervals during which observations of the distance of the moon from the sun, or from a star, cannot be obtained. These instruments would alone accomplish the end proposed, if it were possible to construct them with such accuracy, that when once regulated to the time under a given meridian, their motion would remain exactly the same during the whole continuance of the voyage ; for they would then at all times point...
Page 291 - The water of great rains falls more rapidly, and furrows the sides of the mountains by impetuous irregular torrents. The union of these currents forms streams, which, following the declivity of the ground, unite most frequently in a great canal which takes the name of river, and which conveys to the ocean the collected tribute of the earth.
