the point (B) to the semicircle (CAD) noting also the intersections in the Meridian (CD) Then the diameters (CB) and (AB) being drawne out at both ends, as farre as may suffice, finding in the line (DC) the center of the tenth division from (A) to (C) and from (B) to (C), & of the first point of intersection noted in the meridian frõ the Æquator towards (C) by a way familiar to Geometricians connect the three points, and you haue the paralell of 10. degrees from the Æquator: the like must bee done in drawing the other paralells on either side, the Æquator; as also in drawing the Meridians from centers found in the line (AB) in like maner continued. All which is illustrated by the following diagram.

To describe a Polar Planisphære, draw a circle (ACBD) on the center (E) & as before, inscribe in it two diameters (AB) and (BC) cutting each other at right angles, and the circle into foure quadrants. Each quadrant being deuided into 90. parts, draw from euery 5^th or 10^th of those parts a diameter to the opposite point: these lines all concurring in the center (E) being the pole, are as so many Meridians. Next, hauing cutt the halfe of any one of the former diameters into 9 parts, as (ED) in the points (FGHIKLMN) draw on the center (E) so many circles and these represent the paralells of the Globe, being also here true paralells.
