observations. Both H. and h., in their northern observations, describe it as of 
equable light throughout. It appears from Lord Rosse’s observations that the 
annular form is much more common among these “ planetary ” nebulae than H. 
or h. had any idea of. 
4364 h. 3723=11. 200. On a ground astonishingly rich. 
4368 V. 13. P.D. by Auwers =113° 36' (1830), owing to an error in P.T. (see List of 
Errata). 
4372 h. 3726 = A. 473. There is a singular statement respecting this cluster by Cac- 
ciatore in No. 113 of the Astronomische Nachrichten. He observed it as a 
nebula, he says, on the 19th of March, 1826 (of course, therefore, Dunlop has 
the priority in point of date). But where he saw it Lacaille, he says, noted 
his star 1483 (Ccelum Australe). Also, Piazzi in 1794 and 1801 in the same 
place saw only a star. Cacciatore in 1809 and 1810 observed the same star, 
but saw no nebula, only a star 9m following it (P. xvii. 341, 346). In looking 
for the comet of 1826, however, “fui colpito,” he says, “ da questa bellanebu- 
losa.” Unfortunately for this curious history, the place of Piazzi’s star referred 
to (and which he identifies with 1483 C.A.) differs by no less than 18' in P.D. 
from that of the nebula in question, which was therefore out of the field of 
view, both of his own and of Piazzi’s telescope, when observing the star. 
4390 h. 2000. 2. 6. Omitted by Auwers from his catalogue of new nebulge, which con- 
tains many far less remarkable. Diameter, according to D’Arrest, =7" , 05. 
Bessel’s place =h. +0 S, 8, —0' 22". 
4397 h. 2Q04=M. 24. H.’s two observations hardly consist with this description, and 
their deviation in R.A. of nearly 4 m from Messier’s place makes it very doubt- 
ful whether he really saw this object. 
4411 M. 69. Piazzi, in a note on xviii. 122 of his catalogue, says that both M. 69 and 
M. 70 are 1° more to the south. But he is wrong. 
4415 Auwers, N. 40. This is the nebula discovered by Tuttle on Sept. 1, 1859, and it 
would appear to be variable, for M. D’Arrest says (in a letter of May 8, 1863), 
“ La nebuleuse de M. Tuttle (Astron. Nachr. No. 1337. p. 272) etait, le 24 Sept. 
1862, si brillante et si remarquable dans le chercheur ( grandis et prceclara, ovalis, 
2' longa, 80" lata), que je suis persuade qu’elle n’a pas ete telle du temps de 
Messier et de votre pere, et de vos propres observations. Voici la position que 
j’ai obtenue. 1861-0 R.A. 275° 55'*6, N.P.D. =15° 30'T.” The place given in 
the present Catalogue is that of M. Auwers, and differs somewhat, though not 
considerably, from this determination. 
4428 M. 70. See the note on No. 4411. 
4462 III. 742. This agrees too well with M. D’Arrest’s place of his No. 113 not to 
be the same. His description is F; S; R; #10p -12 r *6, s 2' 30". 
4473 Auwers, N. 44. This is the nebula discovered by Mr. Hind on March 30, 1845.
