DESCRIPTION-(Continued)

Bright diffuse nebulosity 5' x 4', 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.

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.

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 de-
creases 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.

DESCRIPTION-(Continued)

Round; diameter 0:6. Stellar nucleus surrounded by a faint ring; doubtless a spiral, though it strongly resembles a planetary.

0.5 in diameter; round; bright, almost stellar nucleus; perhaps spiral. 5' n.f.
is a bright elongated patch 0:4 long; perhaps spiral.

Faint nearly round spiral 1' in diameter; almost stellar nucleus of magn. 14.
Whorls are very faint and regular, giving a ring effect. 7 s.n.
Rather faint; round, 0:5 in diameter; small nucleus. The whorls form a faint
ring. 6 s.n.

An unsymmetrical oval ring 1' long in p.a. 95°, with several condensations and
an eccentrically placed, hazy nucleus; much fainter matter outside in major
axis. Appears to be a rather irregular single-whorled spiral. Moderately
bright. 12 s.n.

These are very small, almost stellar nebulae, of no particular interest.

Described as "Long patch of F neby." Non-existent? No trace found in an exposure of 2h. 6 s.n.

Moderately bright, very compact, nearly round spiral 0.9 in diameter; almost
stellar nucleus.

Slightly elongated, l' long; very bright center; probably spiral.

2' x 0.5 in p.a. 125°, with very bright round center; no evidence of spiral char-
acter. 8' n.f. is a faint spindle 1' long in p.a. 140°. 10 s.n.

Oval 0.7 long; very bright center.

2' x 0.3 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 p-type spiral seen at a considerable angle. A moderately bright, nearly round, structureless patch of nebulosity 0:3 long; probably spiral.

Oval 0.8 long, with very bright, round center.

Vol. VIII, Plate 68. Bright; 3' x 2'5. Two-branched, S-shaped spiral, probably
the best example of this form. Faint, almost stellar nucleus; numerous
almost stellar condensations in the whorls. 6 s.n.

A very sparse cluster of very faint stars, about 4' in diameter. 2 s.n.
Very faint; 6' long by 0:6 wide in p.a. 45°. Has a very faint elongated or
double nucleus; is an irregular spiral seen nearly edgewise. 8 s.n.

densations. Absorption effect on s. side. See Abs. Eff.

A moderately bright spiral 2:6 x 0.6 in p.a. 97°. No nucleus; a straight line of
matter proceeds to west from the center along the major axis. Apparently
a single-whorled spiral, showing a few rather hazy condensations. 11 s.n.

A replica of 7579.

A narrow spindle 0.8 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.

A faint, slightly oval spiral 1' x 0.8 in p.a. 90°; faint, almost stellar nucleus. 36 s.n.

A beautiful, moderately bright spiral 6' x 1'6 in p.a. 150°. Bright nucleus; whorls are narrow and rather compact. 12 s.n.

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 0.5 long, showing traces of spiral structure. Th two nebulae at the north form an unusual combination. The northern one is 0:3 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.

A rather faint, symmetrical, open spiral 2:5 long; slightly oval. Nucleus almost
stellar and three almost stellar condensations in the whorls. Perhaps con-
nected with 7752. 6 s.n.

exposures. Described as 30' x 10'. 8 s.n.

Vol. VIII, Plate 70. 3′ x 0.8 in p.a. 132°. Bright; no nucleus or whorls are dis-

Moderately bright spiral 3' x 0.5 in p.a. 44°. Small, hazy nucleus; a number
of condensations in the rather compact whorls. See Abs. Eff. 9 s.n.
