1873, Jan. 2. Several stars of the 14 m. precede ; a very sbarp stellar nucleus 
of about 14 m. seen with power 414. Other stars measured as follows :—

1873, Dec. 19. Blue planetary nebula. A small stellar nucleus with a bright 
atmosphere surrounded by a fainter one. There is a very small vacuity close 
to and sf the nucleus:—power 414. Outside diam. np and sf—4d""1 ; 
diameter of bright atmosphere—18"-4. With power 625 the nucleus seemed 
quite granular and surrounded by a narrow dark ring extending quite round. 
Position of two of the more conspicuous central granules=81°-2. 
1875, Dec. 22. Edge diffused, * 12 m. Pos. 106°-4 (2), Dist. 341-3 (2). 
1875, Dec. 24. Is the Nucl. excentric, np centre? The disc seems granular and 
is of a green blue colour. * 12m. Pos. 124°-5 (2), Dist. 293'3 (2). 
1877, Dec. 6. Very irreg. outline, with lower power I thought first it was 
hexagonal, with the higher onee Epf. Looks rather r. (VIII. obs.) 
831 | VIII. 85 | 1872, Oct. 13. Coarse Cl., stars 9, 10-12 mag. Towards the n side is a D * 
92 m. and 11 m., yellow and blue, Pos. 344°-7, Dist. 39'-0. (1. obs.) 
835 1875, Dec. 5. eS, almost stellar, vsb M=* 14m. A * 13m. Pos. 188°°5 (2), 
Dist. 103':3 (2) [This does not agree with d’Arrest, his A a should evidently 
be 1:18 and not 11*-8], 836 was searched for after 835, but was not found. 
{ Not found by d’ Arrest, 1=835]. (1. obs.)

III. 490 | 1856, Nov. 29. vF,S. See no * in it. 
1862, Nov. 16. F,S,gbMN. 5’'fa*12m. (III. obs.) 
839 1872, Oct. 11. Hind’s variable neb. not found. 
1876, Dec. 12. Nothing decisive, sev e F patches suspected. Struve’s Nova is 
certainly not now like what it was in 1868 or I would have seen it with more 
certainty. Sky bright. 
1877, Jan. 9. Found the exact spot by means of the Bonn-maps. No neby. seen 
with certainty near the *. I looked especially sp, but could not see anything. 
Some object in Pos. 257°.5+, Dist. 231''+, I am almost sure it was only a * 
14-15 m., probably the * to which Struve’s Nova from 1868 was then attached 
[Astr. Nachr. No. 1689]. Sky not very good for this sort of obs.’ and speculum 
not recently polished. (III. obs.) 
[Compare Dreyer’s Supplement to the Gen. Cat., p. 389.] 
847 II. 768 | 1873, Jan. 17. Decidedly cometic in appearance, with the head np. Position 
of elongation 111°-2. Has an 11 m. reddish * Pos. 359°-0, Dist. 45"-0. This 
* is the s member of a double star. There is also a 15 m. * f in the direction 
of the axis of the nebula. This object although of the second class is three 
or four times as bright as I. 258=G. C. 793. (I. obs.)
