A tutor to astronomie and geographie, or, An easie and speedy way to know the use of both the globes, coelestial and terrestrial in six books : the first teaching the rudiments of astronomy and geography, the 2. shewing by the globes the solution of astronomical & geographical probl., the 3. shewing by the globes the solution of problems in navigation, the 4. shewing by the globes the solution of astrological problemes, the 5. shewing by the globes the solution of gnomonical problemes, the 6. shewing by the globes the solution of of [sic] spherical triangles : more fully and amply then hath ever been set forth either by Gemma Frisius, Metius, Hues, Wright, Blaew, or any others that have taught the use of the globes : and that so plainly and methodically that the meanest capacity may at first reading apprehend it, and with a little practise grow expert in these divine sciences / by Joseph Moxon ; whereunto is added Antient poetical stories of the stars, shewing reasons why the several shapes and forms are pictured on the coelestial globe, collected from Dr. Hood ; as also a Discourse of the antiquity, progress and augmentation of astronomie.

PROB. XIV.

To observe with the Globe the Altitude of the Sun.

PLace the Globe so that the upper plain of the Horizon may stand parallel to the Plain of the Horizon of your Place; as was taught by the Second Probleme; then turn the North Pole towards the Sun, and place it higher or lower, by moving the Meridian through the notches of the Horizon, till the beams of the Sun pierce quite through the Axis of the Globe: So shall the arch of the Meridian com∣prehended between the Pole and the Horizon, be the number of Degrees that the Sun is elevated above the Ho∣rizon.

Example.

March 20. just at noon, here at London, I would observe the Meridian Altitude of the Sun. Therefore placing the Ho∣rizon Horizontal, as by the Second Probleme: I turn the North

Pole towards the Sun, and move it with the Meridian upwards or downwards, either to this side or that, till I can fit it to such a Position that the Sun Beams may dart quite through the Axis of the Globe; which when it does, I look on the Meri∣dian and find 42. degrees 25. min. comprehended between the Pole and the superficies of the Horizon; Therefore I say the Meridian Altitude of the Sun March 20. here at London, is 42. degrees 25. min.
