[As the distance from the Equator to the Pole cannot be more than a quarter of acircle, or 90°, it is obvious that no place can have more than 90° of latitude; or, inother words, all places upon the earths surface must be between the Equator and 90°of latitude, either north or south.] * Tek-hes-tri-al, from terre, the earth: pertaining to the St. Paul says, 1 Cor. xv. 40, There are also celestial bodies, andbodies terrestrial; but the glory of the celestial is one, and the glory ofthe terrestrial is another.

What are Parallels of Latitude ?Circles either Xorth or South, of the Equator, and running parallel to it. [We may imagine any conceivable number of parallelsbetween tbe Equator and the Poles, though upon mostmaps and globes they are drawn only once for every tendegrees.] 97. What are the Tropics 1 Two parallels of latitude, each23° 28 from the Equator. 98. What are they called respectively?The Southern is called the Tro- jnc of Cancer, and the Northernthe Tropic of Capricorn. [1. The Tropical Circles are shown at E E in the an-nexed figure. 2. The sun never shines perpendicularly upon any points on the earth further fromthe Equator than the Tropics. Between these he seems to travel regularly, leavingthe Tropic of Cancer on the 23d of December, crossing the Equator northward on the20th of March, reaching the Tropic of Capricorn on the 21st of June, crossing theEq
