What remarkable fish in the polar seas ? TEMPERATURE. The two leading causes which affect the temperature of any region are distance from the equator, and elevation above the level of the sea. In proportion as you go fron the equator towards the poles the cold increases, and in proportion as you ascend above the level of the sea the cold increases. Hence, under the equator, low count: ies are excessively hot and unhealthy, but regions elevated 6.000 or 8,000 feet enjoy a delightful temperature, while at 13,000 or 14,000 feet, the climate is the same as in the frozen zone, and at 15,000 feet is the region of perpetual congelation, where ice never melts, and all mountains are covered above this height with eternal snow. The following table shows the mean tenperature at the level of the sea, in all the successive latitudes, and the height at which perpetual congelation takes place. Latitude. Perpetual Congelation.
