NGC a s DESCRIPTION— {Continued)

7129 21 40.7 +65 39 Bright diffuse nebulosity 5'x4', involving five stars of magn. 9-10. The structure is quite irregular; there is a long curved quasi-whorl, but the nebulosity is not of spiral type. 2 s.n. 7133 21 42.1 +65 42 Faint diffuse nebulosity about 3' long involving two stars of magn 12. Perhaps merely an extension of 7129.

Planetary.

Coarse, sparse cluster of stars of magn. 11-15, about 10' in diameter.

Rather faint, compact, very symmetrical spiral; nearly round; 1' in diameter; faint, rather hazy nucleus. 4 s.n. II 5146 21 49.6 +46 48 A very interesting mass of diffuse nebulosity surrounding a star of magn. 9.5.

The nebula shows a great deal of structural detail, including several dark lanes, which are quite irregular. The nebulosity is about 10' in diameter. Very clearly marked effects of dark occulting matter are shown around the nebula over an area about 16' in diameter; the number of faint stars decreases very abruptly. First noted by Espin, A. N., 3633. A photograph by Wolf is reproduced in M. N., 64, p. 838, showing that the nebula is at the end of a long starless rift which extends 2° west to a large mass of faint diffuse nebulosity. The Crossley negative is reproduced in Publ. Astr. Soc. Pac., 29, 94, 1917, Figure 2. 0 s.n. 7177 21 55.9 +17 16 Bright, compact, slightly oval spiral 3' long in p.a. 80°. Nucleus rather large

and indistinct; no condensations in the whorls. 17 s.n.

Bright narrow oval V long in p.a. 65°; slight trace of spiral formation.

Moderately bright spiral 5'x 1' in p.a. 60°. Nucleus bright, but hazy; whorls show no condensations. Some evidence of occulting effect on the north. See Abs. Eff. 21 s.n.

Vol. VIII, Plate 66. 215 x 2' in p.a. 85°. Central portion very bright, with an almost stellar nucleus.

The branched

effect noted in the N. G. C. is not at all prominent. 0 s.n.

7369 22 39.6 +33 48 Round; diameter 016. Stellar nucleus surrounded by a faint ring; doubtless

a spiral, though it strongly resembles a planetary. 22 40.4 +33 28 015 in diameter; round; bright, almost stellar nucleus; perhaps spiral. 5' n.f.

7463 22 56.9 +15 27 2'x013 in p.a. 95°; moderately bright. No nucleus apparent. Very irregular;

the most prominent feature is a bright band cutting across the nebula at an angle of about 50°. Perhaps a 0-type spiral seen at a considerable angle.

7464 22 57.0 +15 27 A moderately bright, nearly round, structureless patch of nebulosity 013 long;

probably spiral.

7465 22 57.1 +15 26 Oval 018 long, with very bright, round center.

7479 22 59.9 +11 47 Vol. VIII, Plate 68. Bright; 3'x 215. Two-branched, S-shaped spiral, probably

A narrow spindle 018 long in p.a. 135°; moderately bright nucleus. A faint double nebula is 1' s.; it is not certain to which object the N. G. C. description applies. 7601 23 13.7 + 8 41 A faint, slightly oval spiral 1' x 018 in p.a. 90°; faint, almost stellar nucleus.

36 s.n. 7606 23 13.9 — 9 2 A beautiful, moderately bright spiral 6' x 116 in p.a, 150°. Bright nucleus;

whorls are narrow and rather compact. 12 s.n. 7609 23 14.4 + 8 57 There is a group of four small nebulae at this point, and it is not certain to

which of the four the N. G. C. description is intended to apply. The two southermost nebulae are small spindles K5 long, showing traces of spiral structure. Th two nebulae at the north form an unusual combination. The northern one is 013 in diameter; slightly oval; rather bright. 27" distant in p.a. 130°, is a similar fainter nebula; a single curved whorl connects the two nebulae.
