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.

The Day of the Moneth given is March 20. so that by the fourth Prob. you have the Suns Place ♈ 10; and by the fifth, the Declination of the Sun 3. 55. North: therefore the Declination being North, and you on the North side the Equator; you must substract 3. 55. from the Meridian Altitude 42. 25. and there remains 38, 30. for the heighth of the Equinoctial above the Horizon; but if your Declination had been South, you must have added 3 55. to the Meridian Altitude, and the Sum would have been the Elevation of the Equinoctial. Having the Elevation of the Equinoctial, you may easily have the Elevation of the Pole; for the one is alwaies the Complement of the other to 90. Thus the Height of the Equinoctial 38. 30. subtracted from 90. leaves 51. 30. for the Elevation of the Pole, here at London. And thus it follows, that the Latitude of any Place from the Equinoctial, is alwaies equal to the Elevation of the

Pole: for between the Zenith and the Equinoctial is contained the Complement of the Heighth of the Equinoctial above the Horizon to 90.
