Not illustrated. 1809 edition. Excerpt: ...on the tides, as in the case of its being infinite. We may therefore consider the ocean as constantly in equilibrio, under the action of fictitious bodies, which produce tides of the third class, which may be determined in this hypothesis. These tides are very small, but are nevertheless sensible at Brest, and correspond to the result of calculations. I have entered into a long detail on the tides, because it is the nearest and most perceptible result of the celestial attractions to us, and one most worthy the attention of philosophers. We see, by the exposition which I have made, the agreement of the theory of the tides, founded on the law of universal gravitation, with the phenomena of the heights and interval of the tides. If the Earth had no satellite, if its orbit was circular, and situated on the plane of the equator, we should only have had, to have enable us to recognize the action of the Sun upon the ocean, the hour of high water always the same, and the law of its formation. But the action of the Moon, combining with that of the Sun, produces in the tides varieties relative to its phases, which, by their agreement with observation, give a great probability to the truth of the theory of gravitation. All the inequalities of motion, produced by the declinations and distances of these two bodies, give rise to a number of phenomena, which, being recognized by observation, place this theory out of the shadow of doubt. It is thus that the varieties in the action of causes, establish their existence. The action of the Sun and Moon on the Earth, a necessary consequence of the universal attraction, demonstrated by all the celestial phenomena, being directly confirmed by the phenomena of the tides, ought to leave no uncertainty on the subject. more
