The description and use of the universall quadrat.: By which is performed, with great expedition, the whole doctrine of triangles, both plain and sphericall, two severall wayes with ease and exactness. Also the resolution of such propositions as are most usefull in astronomie, navigation, and dialling. By which is also performed the proportioning of lines and superficies: the measuring of all manner of land, board, glasse; timber, stone. &c. / By Thomas Stirrup, Philomathemat.

CHAP. XXXIII. Having the latitude of the place, and the Declina∣tion of the Sun, to finde his height in the vertical Circle.

FIrst, set the Sphere to the latitude given, then count the Declination given among the Almicanters from both ends of the Horizon towards the Zenith, and there∣to

place the threed parallel to the Horizon, and where the threed so placed cutteth the Axletree-line, or six a clock hour-line, there is the altitude required.

As in the latitude of 52 deg. 30 min. the Declina∣tion of the Sun being 11 deg. 30 min. if you count this 11. deg. 30 min. from both ends of the Horizon among the Almicanters, and place the threed thereto, it shall lie parallel to the Horizon, and cut the Axle-tree-line at 14 deg. 33 min. and such is the Suns height, when he is di∣rectly in the East or West points which was required.

Or if you place the Horizon to 52 deg. 30 min. in the limbe counted from the Equator, and count the Declina∣tion upon the Axletree-line, viz. 11 deg. 30 min. the parallel thereof shall cut the Horizon at 14 deg. 33 min. for the height of the Sun in the vertical Circle, the same as before.
