SIR J. E. W. HERSCHEL’S CATALOGUE 
No. 
a misprint in P.T. (see List of Errata) accounts for the difference of the minute 
at least. 
708) III. 959 ; I. 60. The catalogued places contradict the described position sf and 
709] np; but this is owing to the error in R.A. of I. 60, which D’Arrest makes less 
by 40 s , which would place I. 60 at 3 h 19 m 35 s (1860). 
710 Au. N. 17. The discovery of this nebula is attributed by Au. to Schonfeld in 
1858, but it seems to be identical with that described by Tuttle (Astronom. 
Notices, xix. p. 224). Auwers’s place is preferred, Tuttle’s being only approxi- 
mate. 
768 Au. N. 18. The celebrated variable nebula of Tempel, discovered Oct. 19, 1859. 
774 II. 594. Auwers considers this as identical with II. 548, with 1° mistaken in P.D. 
778 h. 309=1. 155. Auwers makes the It. A. of I. 155 for 1839= 3 h 53 ra 33 s , destroy- 
ing the identity of these two nebulae. But his place is deduced from an erro- 
neous entry in P.T. (see List of Errata). C.H., by 2 observations in sweeps 
608, 638 agreeing to 3 s in R.A. and 2' in P.D., gives a place which, brought 
up to 1830, gives R.A. 3 h 37 m 58 s ; P.D. 94° 29' 7". 
810. h. 311 =IV. 69. M. D’Arrest found the nebulous atmosphere around the central 
star of this nebula very conspicuous with the Leipzig 4^-inch refractor. 
826 h. 2618 =IV. 26. D’ Arrest’s R.A. is preferred, that of h. 2618 being clearly 
shown to be erroneous. 
836 II. 464. The P.D. is given by W.H. as the same with that of 44 Eridani. 
C.H., using an erroneous place of this star, makes the P.D. 5' too small. 
This is here corrected, and the result agrees with Auwers. 
839 Auw. N. 20. This is the remarkable variable nebula discovered by Mr. Hind on 
Oct. 11, 1852. M. D’Arrest testifies to its complete disappearance on the 3rd 
and 4th of Oct. 1861, “ Hujus nebulae — ne umbram quidem detegere valeo.” 
— “ Ccelo serenissimo regionem summa cura perlustravi adjuvante Dr. Schjel- 
lerup. Nebula reverd deest.” (In 1855 and 1856 it was found by M. D’Arrest 
within 2' of Mr. Hind’s original place.) On Dec. 29, 1861, it was seen by 
M. Otto Struve with the great Pulkowa refractor, but so excessively faint as to 
be barely within the power of that instrument. On March 22, 1862, with the 
same telescope, it was again seen, but considerably brighter, so as to bear a 
faint illumination of the wires. 
851 h. 314=111. 587. Not seen by Lord Rosse, once looked for, clouds passing. See 
notes on Nos. 639, 646, &c. 
880 h. 322. The bright star preceding is v Eridani. 
908 h. 333=11. 547. Not seen by Lord Rosse, once looked for. See notes 132, 
472, &c. 
926 h. 335. Erroneously identified in my Catalogue of 1833 with III. 453 (No. 981). 
See the note on that nebula.
