SIE J. F. W. HEKSCHEL’S CATALOGUE 
No. 
List of Errata), Auwers has given the place of this nebula (1830) as It. A. 
14 h 41 m 3 s ; Decl. +60° 5'. 
h. 1934, &c. In Lord Rosse’s diagram of the group h. 1934, A, the most con- 
spicuous, would naturally be selected as identical with that nebula, but in that 
■ case II. 766 would not be included in the group. On the other hand, if B be 
taken for h. 1934, the identifications will stand as follows: — A=No. 4131 
=11. 766; B=No. 4128=h. 1934; C=No. 4127=1934, b; D=No. 4124 
=1934, a. This, however, supposes an error of 45 s of B.A. in H.’s place of 
II. 766, which is not probable, while on the other hand it is difficult to account 
otherwise for its not having been noticed at all. All things considered, I have 
thought it best to enter A as a new nebula, No. 4133=1934, c, leaving 766 
untouched. 
4167 h. 1948=111. 74. Not seen by Lord Rosse, once looked for (see note on No. 132). 
4173 h. 3624=M. 80. This is Pogson’s globular cluster, with a variable star in the 
centre, for whose most singular history see the Monthly Notices of the R. Ast. 
Soc. xxi. pp. 32, 33, by Mr. Pogson. Mr. P. in that statement says that Sir J. 
Herschel (among others mentioned) had described it as either “ cometary ” or 
“ nebulous.” This is incorrect. In both my observations of this object it 
stands described as a globular cluster, all completely resolved into stars. (See 
C.G.PI. h. 3624.) 
4234 h. 1970 = 2. 5. D’Arrest calls this planetary nebula blue. The place used is a 
mean of his observations, that of h. (Catal. of 1833) being only Struve’s roughly 
brought up. M. D’Arrest makes the diameter =14" , 6. 
4247 III. 727. The comparison of the place here set down with that of Auwers is 
curious for the great number of perfectly accidental errors which have heaped 
themselves together. The place (C.H.) is rightly reduced by her from a Her- 
culis, f 16 m 11 s ; n O' 14", which is that given in P.T., and which, reduced to 1830, 
gives for the R.A. 16 h 44 m 46 s, 8 and for the P.D. 47° 58' 16", differing -f- 8 S *8 
and -f 11" from the exact result. In M. Auwers’s catalogue it is entered thus: 
III. 127; R.A. 16 h 14 m 47 s ; Decl. +43° P (corresponding to P.D. 46° 59'). 
That is to say, there is a misprint in each of the three particulars. This is not 
to be taken as a specimen of M. Auwers’s work, which is an admirable example 
of painstaking devotion, and far beyond any eulogy in my power to offer. But 
it is a striking instance of the way in which, in the great run of chances, 
unlucky coincidences will happen. 
4259 h. 1974. Doubtful whether a nebula or a very faint double or triple star. 
4294 M. 92 (= also Lalande No. 31544). Not observed by h., but 8 times by H. 
Place from Wollaston’s catalogue, which is almost identical with Auwers 
(A.R.A.=0 s T, A.P.D.=0' 3"). 
4302 h. 1981 =h. 3686 =IV. 11. The annular form only perceived in the southern
