Observations of Nebule and Clusters of Stars. Nef 
1855, Dec. 7. Comp. neb. s of 210 seen. Lord Rosse remarked that 5

1856, Dec. 18. Centre of 208 r? Light of 210 patchy round the ao 
centre as if a broken annulus ? 
1857, Oct. 22. I verified the neb. s of 208; 210 is 1, mottled, has Nucl. per- 
haps of annexed shape. Clouded. 
1857, Nov. 15. S * closely f 208, a fainter * seen p and another in the neb. by 
Lord Rosse. 210 suspected r.

521 912— | 1866, Sept. 28. Larger and contains brighter stars than G. C. 512. Has three 
VI. 34 red stars in or near, two (f by diag.) of them are as large as any star save 
one in the cluster. The other is somewhat smaller and near the centre (n by 
diag.). 3 ft. Newtn. 
1866, Sept. 29. Examined with the 3 ft., saw the three red stars noted last 
night and two more between this cluster and G. C. 512, one 
of them, doubtless, being that one of the three recorded on 
Sept. 13, 1850, which I failed to see last night. There are 
thus five red stars in the cluster not differing much either 
in magnitude or shade of colour. None of them are 
in the most compressed part of the field. One of the 
stars near 1st [this?] cluster had, I fancy, a bluish tinge ; 
it was smaller than the red ones, perhaps of the 10th mag. 
The cluster, as seen in a single lens of low power, certainly 
seems seen through, i.e., the stars do not fade away by 
insensible gradations, and they are seen projected on a 
black sky. The diagram roughly represents the position 
of the five red stars. f the cluster is a pair (red and blue) 
about the distance between the clusters ; a and are those not previously 
recorded; the others were seen in 1850. [One of the red stars, probably 
a, was seen by h on Dec. 9, 1831]. a is, perhaps, smaller and fainter red 
than the other four. 
1866, Oct. 29. Verified in the 6-foot the five red stars seen before in the 3-foot. 
h calls one of them which he saw “ruby”; to me they appear of the same 
hue as a Orionis, though somewhat deeper in colour. 
1873, Sept. 21. Contains a single red star to the s and two on the nf side. 
The single star is the reddest of all [Schjellerup, No. 20.] (WIL, obs.) 
523 216—= | 1852, Sept. 17. A * in the edge, perhaps cometary or like a snowdrop. Sky 
IIT. 486 very light. (J. obs.)
