lxxxvii 페이지 - Softer than the softest down, more impalpable than the finest gossamer-- it leaves the cobweb undisturbed, and scarcely stirs the lightest flower that feeds on the dew it supplies; yet it bears the fleets of nations on its wings around the world, and crushes the most refractory substances with its weight. When in motion, its force is sufficient to level the most stately forests and stable buildings...
47 페이지 - Such being the case, we can now prove that the vast amount of salt brought into the Mediterranean does not pass out again by the Straits. For it appears by Captain Smyth's soundings, which Dr. Wollaston had not seen, that between the Capes of Trafalgar and Spartel, which are twenty-two miles apart, and where the Straits are shallowest, the deepest part, which is on the side of Cape Spartel. is only 220 fathoms.
46 페이지 - Wollaston,* who analyzed this water obtained by Captain Smyth, truly inferred that an under-current of such denser water flowing outward, if of equal breadth and depth with the current near the surface, would carry out as much salt below as is brought in above, although it moved with less than one-fourth part of the velocity, and would thus prevent a perpetual increase of saltness in the Mediterranean beyond that existing in the Atlantic.
lxxxviii 페이지 - The animal grinds down the fibre and the tissue of the plant, or the nutritious store that has been laid up within its cells, and converts these into the substance of which its own organs are composed. The plant acquires the organs and nutritious store thus yielded up as food to the animal, from the invulnerable air surrounding it.
cv 페이지 - ... prepare at once two calamities for future generations ; the want of fuel, and a scarcity of water. Trees, by the nature of their perspiration, and the radiation from their leaves in a sky without clouds, surround themselves with an atmosphere constantly cool and misty.
cv 페이지 - ... they furrow during heavy showers the sides of the hills, bear down the loosened soil, and form those sudden inundations, that devastate the country. Hence it results, that the destruction of forests, the want of permanent springs, and the existence of torrents, are three phenomena closely connected together.
cv 페이지 - By felling the trees that cover the tops and the sides of mountains, men in every climate prepare at once two calamities for future generations, the want of fuel and scarcity of water.
47 페이지 - ... than at the surface, we may presume that the excess of salt may be much greater at the depth of two or three miles. After evaporation, the surface water becomes impregnated with a slight excess of salt, and its specific gravity being thus increased, it instantly falls to the bottom, while lighter water rises to the top, or flows in laterally, being always supplied by rivers and the current from the Atlantic. The heavier fluid, when it arrives at the bottom, cannot stop if it can gain access to...

In all these particulars, the meteoric showers of 1834, 5 and 6, have resembled that of 1833 ; while no person, so far as I have heard, has observed the same combination of circumstances on any other occasion within the same period.
