Sun's Wire along with it 5 by which means the 
Moon’s Age is always counted from the Sun : And 
the Moon's Wire being turned fo as to be under 
the Day of her Age on this Plate, will fet her at her 
due Diftance from the Sun for that time. Thefe 
Wires being Quadrants from <7 to H y and from B 
to /, muft Bill keep the Sun and Moon direftly over 
the Ecliptic 5 becaufe the Center of their Motions 
at C and B is perpendicularly over the Pole 
of the Ecliptic in the Arblic Circle. But, becaufe 
the Moon does not keep her Courfe in the Ecliptic, 
as the Sun appears to do, but has a Declination of 
5 J Degrees on each Side of it in every Lunation, 
(he is made to fcrew on her Wire as far on both 
Sides as her Declination or Latitude amounts to. 
For this Purpofe K is a fmall Piece of Pafteboard, 
to be applied over the Ecliptic at right Angles s the 
middle Line 00 handing perpendicularly thereon. 
From this Line there is 5*| Degrees marked on each 
Side upon the outward Limb 5 which reaching to the 
Moon, makes her to be eaftly adjufted to her Lati- 
tude at any time. — AT. B. The Horizon fhould be 
fupported by two femicircular Arches, inftead of the 
ufual Way of doing it by Pillars j becaufe the Arches 
will not flop the Progrefs of the Balls, when they 
go below the Horizon in an oblique Sphere. 
To rectify the Globe . Elevate the Pole to the La- 
titude of the Place ; then bring the Sun’s Place in the 
Ecliptic to the brazen Meridian, and fet the Hour- 
Index to XII at Noon: Keeping the Globe in this 
Pofition, flacken the Screw E y and fet the Sun di- 
reftly over his Place in the Meridian 5 which done, 
fet the Moons Wire under the Day of her Age for
