"The principal part of the aneroid barometer is a cylindrical air-tight box of metal closed by a corrugated top of thin elastic metal. The air is exhausted from the box, which is then sealed. Evidently, the pressure of the air on the outside of the cover will cause the cover to curve inwards, as the space inside of the cover is void of pressure, until the resistance due to the elasticity of the cover, aided by the resistance of a spring beneath it, is equal to the force exerted by the air." — Hallock, 1905

"The inner circle incloses a map upon which the horizontal direction of the lower currents is shown by unbroken arrows, and that of the upper currents by broken arrows. The map is surrounded by a vertical section of the atmosphere in which the up-and-down are also shown by arrows. Near the equator the air rises and moves westward, and near the tropics it moves eastward and descends." -Dryer, 1901

"The general appearance of the aurora is that of an arch of white light rising from the horizon, like the morning down, from which reddish streamers radiate upward, appearing and disappearing in rapid succession, in a series extending along the rim of the arch from one extremity to the other, often with an undulatory motion, the arch continually rising till the streamers sometimes reach the zenith." -Atkinson 1903

"The barometer is simply a pressure gauge that registers the pressure of the air. In this case the cup and tube at the bottom are protected by a brass or iron casing. At the top of the tube is a graduated scale. Attached to the casing is an accurate thermometer for determining the temperature of the outside air at the time the barometric observation is taken." — Hallock, 1905

"A glass tube about 33 inches in length, open at one end, is completely filled with mercury, and being firmly closed by the thumb, is inverted and placed vertically in a cup containing mercury. When the thumb is removed, the mercury sinks in the tube till it stands, generally, about 30 inches above the level of the mercury in the cup, leaving in the upper part a space free of air, which receiveds the name of the Torricellian vacuum." — Chambers' Encyclopedia, 1875

"Suppose a to be a long tube, with the piston b so nicely fitted to its inside, as to work air tight. If the lower end of the tube be dipped into water, and the piston drawn up by pulling at the handle c, the water will follow the piston so closely, as to be in contact with its surface, and apparently to be drawn up by the piston, as though the whole was one solid body. If the tube be thirty-five feet long, the water will continue to follow the piston, until it comes to the height of about thirty-three feet, where it will stop, and if the piston be drawn up still farther, the water will not follow it, but will remain stationary, the space from this height between the piston and the water, being left a void space or vacuum." —Comstock, 1850

"This hygrometer consists of two thermometers a and b similar to each other in all respects except that one of them has a piece of muslin tied closely over the surface of its bulb c, and kept constantly wet by a few threads of cotton which connect it with the water in the vessel d. the water then which rises from the vessel by capillary attraction spreads over the muslin, and evaporates from its surface with more or less rapidity according to the dryness or moistness of the air; and the greater the dryness of the air the greater is the difference between the observed readings of the dry and the wet thermometers." — Encyclopedia Britannica, 1893

When the glacier extends into the sea, the base is undermined by the warmer waters of the ocean, and great fragments are broken off by the waves, forming floating mountains of ice, called <em>icebergs</em>. Icebergs are particularly numerous in the North Atlantic, into which they descend from the extensive Arctic glacial region already described.

During the day the land near the coast becomes warmer than the sea. An ascending current, therefore, rises over the land, and a breeze, called the <em>sea breeze</em>, sets in from the sea, At night the land, from its more rapid cooling, soon becomes colder than the water; the ascending current then rises from the water, and a breeze, called <em>land breeze</em>, sets in from the land.

"Leslie's hygrometer, which is an adaptation of his differential thermometer, is formed by uniting two tubes having a ball blown on the end of each, into which some colored sulphuric ether has been previously introduced. When both bulbs are at the same temperature, the fluid stands at the zero of the scale, but when one of them is covered with wetted paper the instrument shows the depression of temperature of the wetted bulb." &mdash; Encyclopedia Britannica, 1893
