stellav clusters

7. Tlie six dusters in question are tlie following ones: 



N. G. C. 5466. 



In N. G. C. (from G. G.) described as CI, L, vRi, vmC, st. 11 .... Observed 

 by W. Hekschel who places it in class VI embracing »very compressed and rich 

 clusters of stars». Hkrschel describes it as a cluster of extremely small and com- 

 pressed stars of 6' or 7' diameter. Many of the stars visible, the rest so small as 

 to appear nebulous. On the F. A. C. it is shown us as a round nebula containing 

 very faiat stars. Melotte writes: » globular cluster of faint stars». 



N. G. C. 6144. 



Described as CI, cL, mC, ghM, rrr. By W. Herschel classified as VI and 

 described as »a very compressed and cL cluster of the smallest stars imaginable, 

 all of a dusky red colour, the next step to an easily resolvable nebula ». Melotte 

 describes it as a »loose globular cluster, faint ». On the F. A. C. it is seen as a 

 small neb. of faint stars. Spiral? P from M 4. 



N. G. C. 6S38. 



Ci, vL, vRi, pmC, st. 11 — -16, is by J. Herschel described as a mass of closely 

 packed stars, irregular or triangular. Melotte says » appears to be a globular 

 duster». On the F. A. C. the triangular form observed by J. H. well visible, but 

 perhaps due to foreign stars projected on the cluster. 



IC. 4499. 



CI, vF, 4' diam ; 3 F st. in Neb. Found at Arecjuipa by Stewart. Described 

 by Melotte as »globular cluster of very faint stars». It is shown on the F. A. C. 

 as a faint nebulosity with a (foreign) star 13"' (?) in the middle. 



N. G. C. 6496. 



Described in G. C. as Neb. -\- CI, pL, mE, gvlhM. Observed by J. H. in sweeps 

 N:o 454 and 455 and described as CI v rich, irregularly round, inclining to triangular; 

 mE (2' X 90"), 4' or 5' diameter. Many large and small stars in it. Nebulous. 

 On the F. A. P. as »globular cluster of very faint stars. Has a nebulous appearance », 

 d =l'.b. On the F. A. C. shown as small nebulous spot amidst brighter stars. 



N. G. C. 371. 



CI, F, L, R, pC, st. 14 ... 16. In the small Magellanic cloud. Is described 

 by J. Herschel as »duster of the 6:th class, stars 12 ... 15 m, a few = 10 m and 

 one of 9 m, much compressed in the middle; fills field and has loose straggling lines 

 and crooks branching off». Melotte considers it to have »every appearance of being 

 a globular duster». On the F. A. C. it has no resemblance with a globular cluster. 



In all these cases it may be the question about globular clusters, but new 

 examination with higher powers is desirable.
