No. 
declination of this —55° 58'’8. For 58'‘8 read 48'*8, if it be the same object, 
but of that some doubt remains. 
3967 VI. 8. Auwers, using % Yirginis, the determining star in P.T., places this cluster 
in R.A. 14 h 53 m 37 s (1830), 99° 55' P.D. This, however, is declared by a sub- 
sequent MS. note to be a mistake for Mayer’s 577 zod. star, whence the place 
in this Catalogue is accordingly derived. But this star, too, must have been 
mistaken, and on consulting the original sweep (sw. 209, H.) I find no star in 
the sweep whose identity can be satisfactorily ascertained. All that can be 
certainly affirmed is that, within a degree one way or the other in P.D., and 
from 5 to 10 minutes of time in R.A. of the place set down, there exists a fine 
cluster of the 6 th class which should be looked for. Fortunately it is the only 
nebula observed in the sweep, a very short one. 
3977 h. 1866=1. 184. Some suspicion of variability, inasmuch as one description calls 
it R, another E, and another mE, besides other indications in respect of bright- 
ness. 
3998 III. 373. C.H., by three distinct observations in three different sweeps (400, 
730, 917, H.) from the same determining star 11 Librae (s. 0° 13', s. 0° 14', 
and s. 0° 15'), deduces a P.D., which reduced to 1830=91° 49' 39". Auwers, 
using the same star, s. 0° 12' as per P.T., places it in P.D. 91° 17', which, how- 
ever, is probably a misprint for 91° 47'. Two of H.’s observations place the 
small star south, and one north of the nebula. 
3999 h. 1881=11. 576. The binuclear character verified by R, who says that it is a 
close double nebula. 
4016 h. 1892=111. 131. Query if not variable in brightness. H. in two observations 
calls it F and cB; h., in two others, vF and eF. 
4025)11. 756=h. 1898 k In the two observations by H. of II. 756 it is described as 
4029) cF; pL; iF; r; 
pB ; s ; E ; 
and no mention is made of a double star near it, so that though the places agree 
within the possible limits of discordance, they are most probably two distinct 
nebulae. 
4043) 1901, a. Two of six seen by Lord Rosse. The others must have been h. 1901, 
4044/ h. 1902, II. 541 and III. 511. 
4048)111. 886, 887. Auwers has made an error of — 12' in the declination, or +12' in 
4049/ the P.D. of this double nebula as determined from P.T. (20' n. of 7 Serpentis). 
The P.D. here set down is that correctly reduced, C.H. having on her part 
committed an error of +2' in P.D. 
4051 h. 1905=11. 751. In Auwers’s declination, for +20° 44' read +20° 14', an 
evident misprint. 
4065 II. 818. Owing to an erroneous designation of the determining star in P.T. (see
