(32.) A nebula resembling a comet, seen Nov. 7th, 1850, by G. P. 

 Bond, with the Comet-seekei\ 



1850.0 a = 23*^ 50™ 46" 8 = — 33° 24' 



III. Positions of known nebulee have been observed as follows : — 



h. 555. Faintly seen in the Comet-seeker, March 25th, 1852. Com- 

 pared by G. P. Bond with a star of 9.5 mag. Ai'g. Sternverzeichniss 

 -j-60° 1175. Nebula south-following star. 



A a = -f 0™ 26^25 A S = — 1' 57".8 



h. 90. Compared with a star of 7th magnitude B.A.C. 357, by 

 G. P. Bond. Nebula north-preceding star. 



Aa = — 0™ 43^0 A 8 = -\-2' 44".5 



The nebula discovered by Schonfeld in 1858, and numbered 17 in 

 Auwers's catalogue of new nebulte, was also discovered independently 

 by H. P. Tuttle, Feb. 5th, 1859, as "a nebulosity attached to a star of 

 the 9-10 mag. which follows its centre six seconds and is two minutes 

 north of it." It was visible in the Comet-seeker and in the Finder of 

 the Great Refractor. No. 45 of the same catalogue, discovered by Win- 

 necke in 1853, was also discovered independently by H. P. Tuttle, July 

 27th, 1859. It appeared as a faint cometary object in the Comet- 

 seeker, but in the Great Refractor as a cluster just resolved of 2' or 3' 

 in diameter. 



The nebula H, III. 447 was observed Feb. 7th, 1863, with the 

 Great Refractor, by G. P. Bond. Diameter 40", with a faint star or 

 appendage on the north-following side. 



Nebula north-preceding star of 8th mag. H. C. 10303, Sept. 9th, 1863.

The nebula H, I. 288 was observed by G. P. Bond, April 8th, 1859, 

 as follows : — 



Nebula north-following star a of 7 - 8th mag. Oeltzen 9183. 



A a = + 5"' 0^88 A S = + 4' 15".5 



Nebula north-preceding star J of 8 - 9th mag. Oeltzen 9305.
