OF NEBUL2E AND CLUSTERS OF STARS.

Compared with Lord Eosse’s two diagrams of the nebulae composing this group. 
None of them are “novae.” a=h. 449; /3=h. 448; y=h. 447; £=/3; £=y; 
£=h. 446. 
No. 
I =h. 406+1-6 in E.A., and -5' 6" in P.D. 
g =h. 406+ 14 s - 7 in E.A., and —5' 2" in P.D. 
1480 h. 423. This nebula is entered by C.H. as VIII. 1. B, with a remark “ not in print.” 
1508 h. 439 =VI. 6. The E.A. is nearly 2 m in excess of C.H. and of Auwers. 
Examined sweep (h.) 393 in which it was observed. Found all clear and 
correctly reduced.

1533 VIII. 44. Auwers’s P.D. is 84°, instead of 82°, owing to an erratum in P.T. (See 
List of Errata.) 
1578 h. 468=111. 479. No nebulosity seen by Lord Eosse in 5 observations. In H.’s 
single observation the nebula is “ suspected,” and in those of h. it is not posi- 
tively ascertained. The object seems therefore to be merely a small resolved 
cluster of vFst. 
1594. M. 47. Auwers assigns a E.A. greater by 4 m . The cluster has not since been 
observed. It is probably a very loose and poor one. 
1611 h. 480=VI. 37. h.’s P.D. corrected by —10' as the presumed error of reading 
in the single observation obtained. Harding in 1827 (it appears) observed its 
P.D.=100° 10' (for 1830), and W.H.’s place for that epoch is 100° 12', that of 
h. being 100° 19' 4". 
1615 In Lord Eosse’s diagram, a=No. 1617=h. 483; /3=No. 1616=D’Arr. 51; 
1616 - y=No. 1615 = 483, a. D’Arrest’s place for |3 is preferred to that which results 
1617 from comparison with the diagram, h. 284 could not have been in the field, 
being almost a degree distant. 
1633 h. 493=11. 719. h.’s E.A. in P.T. diminished by l m for an error of l m detected 
in the reduction of the observation. This brings it nearer to Auwers. 
1652 h. 3176. Polarissima Australis. This nebula is so near the south pole that its 
precession in E.A. varies from year to year with great rapidity, so that its E.A. 
cannot be computed correctly by the ordinary approximate method. 
The four nebulae h. 508, 510 ; 510, a; 510, b evidently include among them that 
third nebula referred to by Lord Eosse as the accompanying “nova” “forming 
1666 
1667 
1668 
508 — of the last degree of faintness.” h. 507, however, 
is 30° distant in P.D., so that in the observation of Feb. 9, 1850, the P.D. of 
h. 507 must doubtless have been read as 36° instead of 66°, giving rise to a 
mistaken identity with one of the two really new nebulae at that time in view. 
1696 III. 50. I find a memorandum to the effect that this nebula is lost, and was pro- 
bably a comet; but I cannot recover my authority for the statement. It is 
described by H. as “ of the last degree of faintness,” and it is therefore no way
