3. Bring the Sun’s place in the ecliptic to the meridian, and then set the hour index to XII at Noon, and the globe will be rectified _to the Sun’s Place_. If you have a little mariner’s compass, the meridian of the globe may be easily set to the meridian of the place. PROB. VII. _To find the Distance between any two given places upon the Globe, and to find all those places upon the globe that are at the same distance from a given place._ Lay the quadrant of altitude over both the places, and the number of degrees intercepted between them being reduced into miles, will be the distance required: Or, you may take the distance betwixt the two places with a pair of compasses, and applying that extent to the equator, you’ll have the degrees of distance as before. _Note_, A _geographical mile_ is the ¹/₆₀th part of a degree; whereof if you multiply the number of degrees by 60, the product will be the number of geographical miles of distance sought; but to reduce the same into _English_ miles, you must multiply by 70, because about 70 _English_ miles make a degree of a great circle upon the superficies of the Earth. Thus, the distance betwixt _London_ and _Rome_ will be found to be about 13 degrees, which is 780 geographical miles. If you rectify the globe for the latitude and zenith of any given place, and bring the said place to the meridian; then turning the quadrant of altitude about, all those places that are cut by the same point of it, are at the same distance from the given place. PROB. VIII. _To find the angle of position of Places, or the angle formed by the meridian of one Place, and a great circle passing through both the Places._ Having rectified the globe for the latitude and zenith of one of the given places, bring the said place to the meridian, then turn the quadrant of altitude about, until the fiducial edge thereof cuts the other place, and the number of degrees upon the horizon, contained between the said edge and the meridian, will be the angle of position sought. Thus, the angle of position at the _Lizard_, between the meridian of the _Lizard_ and the great circle, passing from thence to _Barbadoes_ is 69 degrees South-Westerly; but the angle of position between the same places at _Barbadoes_, is but 38 degrees North-Easterly. _SCHOLIUM_ The angle of position between two places is a different thing from what is meant by the bearings of places; the _Bearings_ of two places is determined by a sort of spiral line, called a _Rhumb Line_, passing between them in such a manner, as to make the same or equal angles with all the meridians through which it passeth; but the _angle_ or _position_ is the very same thing with what we call the azimuth in astronomy, both being formed by the meridian and a great circle passing thro’ the zenith of a given place in the heavens, then called the azimuth, or upon the Earth, then called the angle of position.
