1183 361— | 1849, Jan. 28. cOrionis. Dark space in the nebula containing nearest companion, 
V. 31 light nearly equable, sketch made with 3 feet telescope [see Phil. Trans. 1850, 
Pl. XXX VIII fig. 16]. All the stars m the neighbourhood are nebulous, 
of these two a little s p last seem to have dark spaces. To the n fof this there 
is another smaller D * susp. to have dark spaces similar to « Orionis. 
1849, Feb. 16. (8 ft.) Last obs”. confirmed. 
1849, March 17. L triple * to s of h 360; confirmed observation of opening in 
its atmosphere, also the openings at D *sp last. [Compare the large drawing 
_ of Nebula Orionis, on which « Orionis and the neb. arms connecting it with 
h 360 are shown]. (At least XI. obs.) 
1184 362 1875, Dec. 5. 2 or 3 groups of a few stars 7-10 mag. not close together. (I. obs.) 
1188 359= | 1856, Dec. 28. Looks like a * enveloped in a v F neb. atmosphere which is 1 E 
IIT. 865 nearly p f. 
1875, Dec. 3. pF (mot at alle F asin the G. C.), v8, R, pg psbM. Looked 
sometimes r. 2 st 13 m. south, a good many others about. 
1875, Dec. 4. Probably v L, vsb MN=* 14 mag. Looks r. A * 12 mag. 
Pos. 64°-7 (4), Dist. 155"-0 (4). (III. obs.) 
1193 3638= | 1850, Nov. 30. «¢Orionis. The luminous appearance extends about 15’ all round 
VY. 34 the star. 
1852, Jan. 24. A B* of 7 mag. f about 75’, with a pretty strongly marked neby. 
round it. (This would require verification, as it clouded immediately). 
1852, Jan. 25. JI think the atmosphere suspected last night round the * f ¢ 
Orionis exists, but as the speculum gave same appearance to some other stars, 
though in less degree, I am doubtful. [This * is probably B.D.—1°, 1004, 
6™-2, 4™ 38° f, 5' 12" n of ¢ Orionis]. | 
1874, Feb. 18. “No nebula about ¢ Orionis (Lord R. and C., 3 foot Herschelian 
_ telescope). 
1878, Jan. 27. No nebulosity seen. [Compare d’Arrest, “Resultate” p. 316]. 
(VII. obs.) 
1202 IV. 33 | 1873, Nov. 15. *9m. with nebulosity in which there is a vacuity pthe *. It 
looks like a comet coiled round into a ring nebula. [See Pl. I.] (1. obs.) 
1225 365= | 1850, Dec. 11. It is I am nearly sure r, probably it is a glob. Cl. At times I 
IV. 34 fancied the centre a little darker and a * in the p part. 
1851, Oct. 23. I strongly suspect annular, r, one * especially seen in p edge. 
1853, Dec. 28. {andy are F st, 6 the fainter; a a B patch or 
a *%, it is near the edge of the neb. Some dark spot or 
spots certainly seen and at times I had a suspicion of a 
concentric ring or rings. 
1867, Dec. 30. 1 E, of unequal brightness, did not see the 
appendages seen formerly. 
1877, Jan. 5. Seems a glob. Cl., stars seen sparkling in it, oval 
sp nf. Edges v dif, especially sf, np edge more sharp. 
Proportion of diameters about 7 : 10.

* 11-12 m. 234°8 174-0. 
There is a F * (14 m +) between the first star and the neb. (V. obs.) 
1226 IV. 24 | 1866, Dec. 7. Saw a pB * but could not detect any neby.; it had a S comp”. p. 
1877, Jan. 12. * 9m. on v F diffused nebulous ground, *8m.sp.also. Belong 
to 1227—V. 28. (AL. obs.) 
1227 V. 28 | 1873, Dec. 22, 26, & 27; 1874, Jan. 9 & Feb. 21. On these nights measures of 
stars in or about the neb. were taken with the 6-ft. The following table 
contains the results. a@—€ Orionis.
