2 MR. J. baxendell's observations of comet I. 1861. 



Turning the 13 -inch reflector upon the comet with powers 

 of 81 and 1 96 J it was found that the nebulosity was more 

 than 20' in diameter, con- 

 siderably condensed in the 

 middle, but without any di- 

 stinct planetary or stellar 

 nucleus. There was a faint 

 tapering elongation extend- 

 ing about a quarter of a de- 

 gree from the north follow- 

 ing side; and stars of the 

 nth and 12th magnitude 

 were easily seen through the 

 comet at the distance of half 

 a radius from its centre. 



May 4th. Three com- 

 parisons with Argelander 

 1 73, 1 22 gave the place of 

 the comet at 9^ 26^ 19^-3 

 G.M.T. R.A. 9^ 52"^ 19^-83, 

 Dec. +45° 18' 28"- 1. 



With the 1 3 -inch reflector 

 the diameter of the nebu- 

 losity constituting the head 

 of the comet, carefully esti- 

 mated by comparison with 

 the known diameter of the 

 field of view, was 22'. It 

 was much condensed in the 

 middle, but jthere was cer- 

 tainly no distinct stellar nu- 

 cleus. The centre of greatest 

 condensation was not in the 

 centre of the nebulosity, but 

 towards the north following 



Comet I. 1861, 



As seen with Mr. Woi'thington's 

 13-ineh Keflector, May 4th.
