They are also more hardy and industrious than those living nearer the equator. The parallels or climata 2 drawn through places, of which the longest day is of equal length and the decimation (distance) from the equator is the same, he maintained, ought to have been inserted at equal intervals, say of half an hour, and the meridians inserted on a like principle. Air from the lower atmosphere enters the stratosphere near the equator, where solar heating is maximum. This is because these counties experience less of a difference in the number of daylight hours than countries that are farther away from the equator. The conspicuous absence of barn owls from regions far north & south of the Equator is probably due to its poor adaptation to cold. An egg has an equator which is smaller than that of a sphere with the same polar radius. This is identical with the angle between the horizontal planes at the place and at the equator, and also with the elevation of the celestial pole above the horizon (see Astronomy). If a mirror is mounted on a truly adjusted polar axis, the plane of the mirror being parallel to that axis, the normal to that mirror will always be directed to some point on the celestial equator through whatever angle the axis is turned.
