The schoole of skil containing two bookes: the first, of the sphere, of heauen, of the starres, of their orbes, and of the earth, &c. The second, of the sphericall elements, of the celestiall circles, and of their vses, &c. Orderly set forth according to art, with apt figures and proportions in their proper places, by Tho. Hill.

An Example.

VIteberge and Westphalia agrée in latitude: that is, they be both standing vnder one Parallell. For the latitude of Viteberge is 51. degrées, and 50. scruples, and excéedeth the latitude of Westphalia by certaine minutes, which here we passe, but they differ in longitude, in that Westphalia lies more to the West. The longitude of Vite berge is 30. degrées, and 30. scruples: the longitudes of Westphalia is 24. deg. & no min. To find the distance, see how many miles answere to one degrée of longitude in y^• parallel, passing by the Zenith of the Citties giuen. Before

was taught, that in the Parallel of Viteberge 9. miles and 16. scruples do answere to one degree: wherefore seek the difference of longitudes of the two Cities, and deduct the lesser number out of the more; that is, let the 24. de∣grées and no minutes bee deducted from the 30. degrées, & 30. scruples, & the difference resting, shall be of 6. degrées, and 30. scruples. Last, multiply the 6. miles and 16. scru∣ples, with the difference of longitude; that is, with 6. de∣grées, and 30. minutes, and you shall haue the distance of the twoe Cities. But here obserue and note diligently in the multiplicatiō of the degrées, miles, and minutes, what procéedeth and commeth of the same. For the miles mul∣tiplied by the degrées, doe bring foorth the miles: and the miles multiplied by the minutes of the degrées, doe bring forth the scruples of the miles. The minutes of the miles multiplied by the degrées, doe produce or bring foorth the minutes of the miles. And last, the minutes of the miles multiplied by the minutes of the degrees, doe produce the seconds of the miles.

But that this may the readier be conceiued, vse this ex∣ample, the former Westphalia and Viteberge: where the 9 miles and 16. scruples, are to bee multiplied by the 6. de∣grees, & 30. minutes on this wise. Multiply the 9. whole miles, by the 6. whole degrees, thus: as sixe time 6. brin∣geth out 54. miles. Multiply after that, the whole miles by the minutes of the degrees; thus, that 9. times 30. doe make 270. minutes of miles. After multiply the minutes of the miles by the whole degrees, and by the minutes of the degrees: as the 16. minutes of the miles multiplied by the 6. degrees, doe make 99. minutes of miles. After this the 16. minutes of the miles multiplied by 30. mi∣nutes of the degrees, doe make 480. secondes of miles; which minutes and seconds gather into whole miles, in this maner. First deuide the 480. seconds by 60. and the quotient shall be 8. minutes. (For that one minute contai∣neth

60. seconds, as one degrée doth cōtaine 60. minutes. These 8. minutes, adde to the minutes procéeded of the former or vpper working; that is, the 270. and the 96. & you shall haue 374. scruples of miles, which deuided by 60. the quotient will be 6. whole miles, and 14. scruples; that is, almost the fourth part of a Germaine mile. These miles gathered of the seconds and minutes of the miles, adde to the 54. miles gathered afore by the multiplica∣tion of the degrées and miles, and you shall haue the true distaunce betwéene Viteberge and the Monasterie of Vest∣phalia; that is, 60. Germaine miles, and almost a quar∣ter.

This maner of working in searching the distance of pla¦ces (which differ in the onely longitude) obserue in the o∣ther examples following: in which you shal finde their di∣stance, by hauing their longitudes and latitudes.

Here folowing shall be sundrie examples, in which the young students and practisers may excercise them accor∣ding to rule.
