When the atmosphere is highly charged with electricity, faint tinges of fire are often seen on the ends of bodies in connection with the earth, like the masts of ship, steeples, etc., due to an electric charge, known as the <em>brush-discharge</em>.

"A representation of a section of a grate and chimney. C D represents the light and warm column of air within the chimney, and A B the cold and heavy column of air outside the chimney. The column A B being cold and heavy presses down, the column C D being light and warm rushes up, and the greater the difference between the weight of these two columns, the greater will be the draught." &mdash;Wells, 1857

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.

One of the best known of the European glaciers is that of <em>Mer de Glace</em> (Sea of Ice). It descends from the slopes of the range of Mont Blanc, and is formed by the confluence of three large glaciers: <em>the Glacier du Geant</em>, <em>the Glacier de Lechaud</em>, and <em>the Glacier du Talefre</em>.

"Summer and Winter rays.&mdash;Let us suppose that the rays falling perpendicularly on a given extent of surface, impart to it a certain degree of heat, then it is obvious, that if the same number of rays be spread over twice that extent of surface, their heating power would be diminished in proportion, and that only half of the heat would be imparted. This is the effect produced by the Sun's rays in the Winter. They fall so obliquely on the Earth, as to occupy nearly double the space that the same number of rays do in the Summer." &mdash;Comstock, 1850
