DESCRIPTION-(Continued)

An oval 1' long with bright central portion; some faint traces of spiral
structure.

An oval with bright center, 1' x 0:3, in p.a. 105°, probably a spiral. This is
near the center of a remarkable field which contains thirteen N. G. C.
objects, and eighty-one other small and faint nebulae.
81 s.n.

A fairly bright, compact spiral 16 x 1'; bright, but not very sharp nucleus,
which is quite asymmetrically placed.

The main whorl of this spiral forms an elliptical ring 35 x 1' in p.a. 95°;
exceedingly faint matter outside brings the total length to nearly 8'. Bright,
rather irregular matter in the vicinity of the nucleus, which is elongated
and shows well in a 5m exposure. See Abs. Eff. 17 s.n.

Nearly round; 0:3 in diameter, with an almost stellar nucleus; a spiral.
Nearly round, l′ in diameter; central part very bright; no spiral structure
discernible.

A very bright oval 1.5 x 0.5; some slight indications of spiral structure.
About 0.6 long in p.a. 110°; bifid. See Abs. Eff.

Round, 0:3 in diameter; quite bright; structureless.

Very faint; slightly oval; 1' long; faint stellar nucleus; probably spiral.
A faint spindle 0.8 long in p.a. 80°; spiral.

Slightly oval; 1' long; a p-type spiral with a bright stellar nucleus.
Bright spindle 1' long in p.a. 125°, with almost stellar nucleus.

Vol. VIII, Plate 34. M. 61. Nearly round; 6' in diameter; very bright. A
beautiful spiral, with a very bright, almost stellar nucleus, and many almost
stellar condensations in its open, somewhat irregular whorls. 40 s.n.
Nearly round; rather bright; 12 in diameter. A p-type spiral with several
almost stellar condensations in its main whorls, which form a nearly com-
plete ring.

Rather faint; 24 x 0.5 in p.a. 170°. Nucleus and whorls indistinct. See Abs. Eff.
Vol. VIII, Plate 35. A bright, regular, nearly round spiral 5′ in diameter.
Very faint stellar nucleus surrounded by bright, short whorls, forming a
central oval. The outer whorls are rather open, quite regular, and show
many stellar condensations. Two novae have appeared in this spiral.
M. 100. 15 s.n.

A spiral of the p-type, 3'6 x 3', with a bright, rather large nucleus.

A spindle 2' x 0.4 in p.a. 30°; very bright; no spiral structure discernible. 28 s.n.
Planetary. 4 s.n.

Very bright oval, 4' x 2'; very slight traces of spiral structure. M. 85. 14 s.n.
1.5 x 0.5 in p.a. 25°, with a large, bright center. The northeastern end is bifid,
with a dark lane extending in to the nuclear portion; no lane is visible at the
other end. No whorls discernible.

0.8 x 0:4; bright center; no spiral structure discernible.
An elongated, rather irregular spiral 3' x 0.4 in p.a. 90°. Nuclear portion fan-
shaped; an irregular dark lane along the major axis. See Abs. Eff.

An irregular spiral 1:8 x 0.8. A bright, somewhat irregular streak lies along
the major axis in p.a. 100°. Most of the nebular matter lies at the ends
of the major axis, and there is evidence of absorption on the northern side.
There is nothing in just this position, though there are several small nebulae
near. The N. G. C. description accords best with a very small, moderately
bright oval 9′ n. and 2' w. of 4389. 31 s.n.

The inner and brighter part is 14 in diameter. Exceedingly faint outer whorls make the diameter about 4. The nucleus is large and very bright. It is a good example of the p-type spiral; the cross-arm is bright and the inner whorls extending from this nearly form a ring.

This appears to be an exceedingly faint, very large, and very irregular spiral, covering an area about 8' in diameter; many almost stellar condensations; no true nucleus. 27 s.n.

Very faint; 3' x 0.5 in p.a. 88°; a patchy, irregular, edgewise spiral with an irregular dark lane down the middle. See Abs. Eff.

Slightly oval, 2′ long; bright center, which is not stellar in short exposures; no spiral structure discernible. 5 s.n.

Non-existent.

Patchy, quite irregular spiral 1.5 x 0.5 in p.a. 10°. Fainter along its western edge; no true nucleus. The position is for 4409, while the description accords with that for 4420; there is no object in the position given for 4420. 9 s.n.

discernible, though spiral character is suspected near the center in the
short exposures.
28 s.n.

Exceedingly bright; the sharp nucleus shows well in 5m exposure. The brighter
central portion is about 0.5 in diameter, and the total diameter about 2';
nearly round. No spiral structure is discernible. A curious straight ray
lies in a gap in the nebulosity in p.a. 20°, apparently connected with the
nucleus by a thin line of matter. The ray is brightest at its inner end, which
is 11" from the nucleus. 20 s.n.

edgewise spiral with dark absorbing lane. This runs down the central line,
just north of the nucleus, which is bright and almost stellar. P.a. 134°.
Several almost stellar condensations. See Abs. Eff. 51 s.n.

Two rather faint spirals so close together that they overlap slightly. The
centers are 12 apart in p.a. 165°. The northern nebula is 2' x 1'; the
southern 3' x 1'. The northern nebula has a very bright, almost stellar
nucleus; that of the southern nebula is double. Both are rather open spirals
with many almost stellar condensations. There is apparently a slight
amount of occulting effect, due to overlapping. See Abs. Eff. 42 s.n.
7' x 1'5 in p.a. 92°; very bright. A remarkable, slightly curved, clear-cut dark
lane runs along the entire length to the south of the nucleus; probably the
finest known example of this phenomenon. There are very slight traces of
spiral whorls. See Abs. Eff. 11 s.n.

curious irregular absorption lane extending along the middle for 0:5 on each
side of the nucleus. See Abs. Eff. 7 s.n.

A faint spiral 2′ x 0.8 in p.a. 170°; faint, almost stellar nucleus.
Vol. VIII, Plate 42. A beautiful spiral 5' x 4' in p.a. 38°. Nucleus very bright;
the whorls are on the periphery of the nebula, there being none near the
center. A wide faint band of matter lies along the major axis of the nebula;
an excellent exemplar of the p-type spiral. Whorls show a number of almost
stellar condensations. 19 s.n.

Vol. VIII, Plates 43 and 44. M. 94. A beautiful object. From the very bright,
large nucleus spring many bright, closely packed whorls, forming a bright
inner oval 2′ x 1.5 in p.a. about 110°. These inner whorls show many stellar
condensations, whose sharpness and proximity to the nucleus would seem to
make this one of the most favorable examples known for the investigation
of motion in spirals. Fainter, closely packed, rather uniform outer whorls
bring the nebula to a size of 5' x 3'5. 17 s.n.

1' long in p.a. 80°; considerably elongated, with very bright round central portion. No spiral structure discernible.

A rather faint spiral 3' x 0.5 in p.a. 30°. Irregular line of brighter matter along the major axis, and evidence of an absorbing lane southeast of the nucleus. Narrow spindle 1' long in p.a. 40°, with bright, small, central portion; structureless.

An irregular, slightly oval spiral 1' long, with a fairly bright, almost stellar nucleus.

Nothing in this position. The N. G. C. description is "cF, S, vS* att.'' There is a small, bright spindle at 12h 51m2, +3°19′, with a star of magn. 15 s.f. 0:8.

Two very irregular, elongated, faint patches of nebulosity; both are probably exceedingly irregular spirals. Their centers are about 40" apart in p.a. 170°. The northern nebula is about 1' long; the southern 0:5, and their major axes are in position angles of approximately 60° and 160°, respectively. No certain evidence of any occulting effect due to overlapping. No nucleus discernible in either nebula. 17 s.n.

Vol. VIII, Plate 45. The central portion of this fine nebula is very bright, and there is a bright, almost stellar nucleus. It is 8' x 4' in p.a. 110°. The whorls are rather compact, and of very uniform texture, without irregularities or condensations. The most striking feature of this spiral is the somewhat irregular, but very clear-cut, absorption area on the north of the nucleus. See Abs. Eff. 2 s.n.

This region contains the most remarkable aggregation of closely packed small nebulae known to me. About thirty are catalogued in this area in the N. G. C., and some twenty-five more are given in N. G. C. II. In reality there are more than three hundred small nebulae in an area about 50' x 40', a large proportion of which are probably spirals. None of them are conspicuous objects. They are so numerous that it is very difficult to locate those catalogued in the N. G. C. with any certainty, except for a few of the brighter objects. See figure 3. 304 s.n.

Quite irregular; 12 long; binuclear.

A small p-type spiral 1.5 long; stellar nucleus.

This is not a planetary; its spectrum is continuous. It is about 0.5 in diameter,
of unusual structure. There is no nucleus; the nebula matter is arranged
in a three-branched effect, much like a short letter Y.

produced in Vol. II of See's Evolution of the Stellar Systems, Plate 1.
Vol. VIII, Plate 47. The beautiful spiral M. 51 in Canes Venatici. Including
very faint matter to the north of 5194, scarcely visible in any of the very
numerous published reproductions, it covers an area about 12' x 6' in p.a.
approximately 30°. A sharp stellar nucleus in 5194, and the whorls show
a multitude of stellar condensations. The satellite nebula, 5195, has a bright,

cernible spiral structure, and with several rifts which suggest absorption
effects. See Abs. Eff. 22 s.n.
