7 Tauri.) Double. Hers, IV. 88. “ Very unequal. L. pr.; 
S.dr. Distance 19°83, Pos. 23°°25 n. following.” 
M.113.) Mayer’s R.A. is +235, and Decl. +2276, but his 
- is a single obs. and marked doubtful. 
9 Tauri.) This star was observed twice by Flamsteed, and se- 
veral times by Bradley (whose observations ascertained the 
position here laid down); also twice observed by Lalande, 
28th Sept. and 28th Oct. 1793, as of the 7th mag. Yet 
Bode and Herschel could not see it, neither is it contained 
in Piazzi’s Catalogue. It may therefore be considered va- 
riable. 
Anon. R.A. 51° 29%.) Hist. Cél., p. 195. Supposed to be 
Herschel’s star III. 78. ‘* Double. About 13° s. prec. 
13 Tauri in a line parallel to <¢ Tauri and @ Ceti. Nearly 
equal. Both pr. Distance 717. Position 87°95 n. 
preceding.” 
C.87.) In Wollaston’s Cat. this star is set down as 87 Mayer. 
Very near it was the planet Ceres when first discovered by 
Piazzi, lst Jan. 1801. 
B. 34 Tauri.) A double star of the third class. Herschel MS. 
Jan. 1785. 
Anon. R.A. 52° 47'.) Hist. Céleste, p. 200. Supposed to be 
Herschel’s double star III. 88. ‘* About 3° north following 
11 Tauri, towards + Aurige. Very unequal. L.w3; S. pr. 
Distance with 278, 13’°6. Pos. 89°°35 n. foll.”’ 
Tue Purves.) In Piazzi’s Catalogue are 28 stars distin- 
guished as belonging to this celebrated group; the whole 
of them are inserted in the present collection, with an ad- 
ditional one from Bradley. Besides these, Bode’s Catalogue 
comprises about 65 more, inserted from the observations 
of Lemounier and Jeaurat; but they do not possess suffi- 
cient accuracy, either of position or magnitude, to justify 
the introduction of them upon the present occasion. Francis 
Baily, Esq. (to whose assistance the present writer acknow- 
ledges himself greatly indebted) has noticed that Jeaurat’s 
stars are incorrectly brought up to the epoch of Bode’s Ca- 
talogue, as the Right Ascensions ase all too little by 217; 
and the Declinations too great by a quantity varying from 
0” to 20”, and depending upon the R.A. of each star. 
The order of brightness among the stars of the Pleiades, 
comprised in the Brit. Cat. is given by Herschel as follows : 
25—, 27. 17. 20, 19..28—, 28, 18. 16. 21, 22, 26, 24. 
Piazzi’s magnitudes agree in general with this arrangement, 
with the exception of those assigned to 17, 28, and 16, which 
are estimated too high, as will be hereafter noticed. ‘Three 
of the stars which Piazzi has classed among the Pleiades,
