exceeding the globe at both ends ; let him place th6 

 supporting hoops *, as also the equinoctial circle. 



** Three circles must be prepared, (divided for 

 signs and degrees,) the radius of which must agree 

 with the respective diurnal circles, in proportion to the 

 equinoctial : the three circles should be placed for the 

 Ram and following signs, respectively, at the proper 

 declination in degrees, N. or S. ; the same answer con- 

 trariwise for the Crab and other signs. In like manner, 

 three circles are placed in the southern hemisphere, 

 for the Balance and the rest, and contrariwise for Ca^ 

 pricorn and the remaining signs. Circles are similarly 

 placed on both hoops for the asterisms in both hemi- 

 spheres, as also for Ahh'i'fit ; and for the seven Rtsh'is^ 

 jigastycjy Brahme and other stars. 



'* In the middle of all these circles is placed the 

 equinoctial. At the intersection of that and the sup- 

 porting hoops, and distant from each other half the 

 signs, the two equinoxes should be determined ; and 

 the two solstices, at the degrees of obliquity from the 

 equinoctial-; and the places of the Ram and the rest, 

 in the order of the signs, should be adjusted by the 

 strings of the curve. Another circle, thus passing 

 from equinox to equinox, is named the ecliptick ; 

 and by this path, the sun, illuminating worlds, for ever 

 travels. The moon and the other planets are seen devi- 

 ating from their nodes in the ecliptick, to the extent of 

 their respective greatest latitudes [within the Zodiack]." 



The author proceeds to notice the relation of the 

 great circles before meutioned to rlie horizon ; and ob- 

 Berves, that, whatever place be assumed for the apex 

 of the sphere, rhe middle of the heavens for that 



• They are the Colures.
