...difference of latitude 30 degrees foutherly, the latitude come to would be io degrees fouth. 6. The height of the pole above the horizon is. equal to the latitude of the place, for it is evidently equal to the diftance of the equator from the zenith. Though the earth is a fphere,...

...upon £. S. £. point of the compass, what is its latitude ? GEOGRAPHICAL AXIOMS. 1st, THE elevation of the pole above the horizon, is equal to the latitude of the place. Sd, The elevation of the equator above the horizon, is equal to the compliment of the latitude. 4th,...

...any other circles, at any given time, and to find the time from their position. 84. The altitude PR of the pole above the horizon is equal to the latitude of the place. For the arc ZE is (16) the measure of the latitude, but PE — ZR, each being - 90°, take away ZP...

...quantities Ae and pr will be equal ; and as A e is the latitude of A, it follows that (pr) or the height of the. pole above the horizon is equal to the latitude of the place. Again, Ap is the distance of the pole from A : and as Ae is the latitude of A, and/)e is 90°, Ap is...

...quantities A e. and pr will be equal; and as Ae is the latitude of A, it follows that (pr) or the height of the pole above the horizon is equal to the latitude of the place. Again, A p is the distance of the pole from A: and as Ae is the latitude of A, and p л is 9(P, Ap...
