SIB J. E. W. HEBSCHEL’S CATALOGUE 
No. 
W.H. twice says mE in merid. (180°) — h.’s position 75° np to sf=165°; a mean 
of those of Winnecke and Auwers =172°. 
2377 h. 857, h. 875; M. 66. No doubt these are tho same. fig. 54 P.T. 1833 corro- 
borates their identity. The accompanying stars and their positions agree 
entirely. The R.A. of h. 875, however, requires to be corrected by — 3 m , 
allowing the seconds and the P.D. observed in that observation their weight. 
2382 II. 30, Auwers deduces his RA. for 1830 (ll h 12 m 21 s ) from the statement in 
P.T. “following 68, h Leonis, 6 m 30 s .” C.H. from the same data concludes 
RA. ll h ll m 31 s (also for 1830). The latter is (within 2 s ) the correct result. 
2388 h. 867 =h. 861 1 These are very probably the same. But as, after all, the difference 
of the observed RA.’s is sufficient to have allowed one to escape while observing 
the other, so that they may be different, and as moreover one is described as 
“Bound,” and the other as “extended,” both are retained. 
2405 h. 882=1. 20. This nebula would seem to have decreased in brightness. The 
bright * is 1341. A.S.C. 
2411 h. 886=1. 131. Ranked by M. D’ Arrest in the second class with the 4-|-inch 
Leipzig telescope. In this Catalogue it stands as “ pretty Bright ” from a mean 
of three observations. 
2417 III. 112. Auwers has reduced this nebula by the star given in P.T. (p, 74 Leonis. 
But I find a MS. note that this star was not dependable, and that Mayer’s 
No. 510 is the proper determining star. The nebula was subsequently looked 
for and found, not in the place given by <p, but 8' from the P.D. concluded 
from Mayer 510. A mean of these two determinations is therefore used in this 
Catalogue. 
2440 h. 907=111. 353. Auwers doubts the identity of these nebulae. But this is in 
consequence of a misprint in P.T. (see List of Errata), 53 m for 43 m . The error 
is found also in the Register Sheet (H. 937), but C.H. has avoided it and used 
43 m in her reduction so as to give a RA. agreeing within 35 s with that of h. 907. 
2461 h. 918=11. 784. Lord Rosse, in his observation of this nebula, mentions 
“ another brush-like, 20' np.” This was no doubt II. 783=No. 2454. 
2501 h. 945=1. 94. W.H. makes this nebula by one observation extended, n to s, 
by another nf to sp, while h. has two observations agreeing in making it extended 
in the parallel. Surely it does not rotate 1 
2540 h. 967. l m added to the R.A. It is evidently the first of the group of 4. 
2577 III. 113. This nebula is reduced also in Auwers’s catalogue by <p Leonis, the star 
set down in P.T. But C.H. remarks that <p was above the sweep, and otherwise 
observed under unfavourable circumstances, and Mayer’s 510 zod. star. s. 0° 31 
is preferred, which gives a result differing by +24' in P.D. and —48 s in R.A. 
The place adopted in the present Catalogue is in conformity with this remark. 
(See note on No, 2417.)
