802 $frged-Shiftd the construction of tho instrument, is here assured to be deferred unbir after all bhe other circles of declination are fixed in their places, The word translated above (ra®u) n verse 10 requires to be tenderstood in two very lifter€tsensus, ue is pointed out by the conm tnontator, to make the definitions of position of the Bustices and of the xquinoxes both correct: the latber are situated precisely b bhe interse. tion of the equinoctial colune with the equabor; the forme' at a distance of 24 above und below the intersection of the oquator with the other oblure, or at the intersection of the colue ith the bhird parallel of the sun's declination, on either side of the equetor. We are next taught how to fix in its proper position the hoop which is the represenk the ecliptic. .

In the compound rgagigi, in verse 11t, which we have rendered “ oblique chords, we conceives yd to have its own more proper meaning of ‘‘ chord, instead of that of Sine, which, by substitution for g%;a (see note to ii, 15-2?, near the end), it has hitherto uniformly borne, We are to ascertain by ealculation the measure of the chord of 30° to reduce it to the state of dimensions adopted for the other great stoles of thhe instrument, and then, commencing from either equinox, to lay it oft, in an oblique direct pion, to the successive diurnal circles, northward and southwa&, “ he
