No. 
are indicated by the letters MS. attached in the column of descriptions. The 
others I identify as follows: — 
a (in Lord R.’s diagram) is No. 1813=582, c. 
j3 „ „ 1812 = 582, h. 
y „ „ 1811=h. 582. 
b „ „ 1806=h. 581. 
g „ „ 1815=582, e. 
£ „ „ 1821=582, g. 
One of those for which no data are given must have been D’Arr. 63, and the 
two remaining ones are included under the entries Nos. 1817, 1818 as 582, f. 
1832 h. 590. Not seen by Lord Rosse; once looked for. Re-examined the sweep and 
reductions. Found all correct. 
1868 h. 3171. In the omitted observations of nebulse in the last page of the C.G.H. 
observations, for h. 3170 read h. 3171; and this observation, combined with 
the two in the body of the work, gives the mean result for 1830 employed to 
deduce the place in the present Catalogue. 
1911 h. 3185=111. 289. In consequence of a misprint in P.T. (see List of Errata), the 
P.D. of Auwers is 5' too small. Corrected by this, his place agrees well with 
my observation. 
1953 M. 81'?'? A nebula observed by W.H. as described, but differing most materially 
in place from M. 81. It would certainly be very extraordinary should three 
nebulae so extremely remarkable as M. 81 and 82 and this be found to lie so near 
together. 
1959 1 h. 3198, 3202 are distinct nebulae, and were observed consecutively in one and 
19621 the same sweep — sw. 561 (h.). 
1960) h. 3199 and 3201 are also distinct nebulae, and were observed consecutively in 
196l! sweep 562 (h.). 
1974 III. 293. M. Auwers makes the place of this nebula 9 h 24 m 4 s ; 66° 30' (1830), 
instead of 9 h 48 m 48 s ; 60° 13'. The cause of the error is an erratum (see List) 
in P.T., where the determining star is set down as 23 Leonis instead of 23 Leonis 
Minoris, another of the instances of confusion arising from the use of this silly 
and barbarous nomenclature. 
2014 h. 669=111. 65. Not seen by Lord Rosse in one observation. It was found by 
h. in its place jper working list. 
2019 h. 672. Not seen by Lord Rosse in one observation. Examined the sweep and 
reductions, and found all correct. 
2043 h. 250. This nebula is so very close to the North Pole, that its place cannot be 
calculated by a precession proportional to the time in the usual approximate 
mode, the R.A. changing from year to year with extreme rapidity.
