gesimal, and T E its distance from thevertex.

In the oblique angled spherical trianglePeEj are given Pe 23° 29', the distanceof the poles of the equator and ecliptic, P E,38° 28' the co-latitude with the included-angle ePE 144 0 48', the complement of35 0 12' the distance of the mid-heavenfrom the first point of W to 180 degrees.The measure of this angle is obtained uponthe equator between the strong brass, and themoveable meridians.

To find the angle P eE, as it is includedbetween © e, the strong brass meridian, ande T the quadrant; we have its measure24° 44/ upon the arch ST of the ecliptic,its complement 65° i6 ; is T T, the longi-tude of the nonagesimal from the first pointof Aries, or tl 5 0 i6 / its distance E T fromthe vertex E, is gained on the quadrant ofaltitude 31 4 2', the complement of which58° 58' is the altitude of the ecliptic abovethe horizon at this time; or it is the anglewhich the planes of the ecliptic and horizonmake with each other; as T is the highestpoint of the ecliptic at this time, and itslongitude in it 5 0 16', three signs'or 90Y 3 degrees
