A triple star, on the back of Taurus, about 3° to the np of the Pleiades. A 6, white; B 6½, pale yellow; C 11, bluish. This is a fine and very difficult object, being Σ's No. 412, "vicinissimæ." A and C point to a comes in the nf quadrant, and constituted 88 ♅. IV., but Sir William did not observe that A was double. It may have opened since. His measures of A and C werePos. 66°45' Dist. 19".833 Ep. 1783.77It was then re-examined by H. and S., No. 363, with these results:Pos. 56°06' Dist. 21".055 Ep. 1821.97and Σ., who first made it a triple object, thus registered it:AB Pos. 269°.92 Dist. 0".692 Ep. 1830.38Now the first two epochs exhibited so great an orbital change, in less than forty years, as to excite much attention; but the accordance of those of Σ. and myself, indicate some error of observation or entry. In this conclusion, however, Σ's angle for 1821.95, in the Dorpat Observations, is rejected; since it must be deemed rather an essay than a conclusive measurement.
