2. The Grt C 1843. 



Owing to an extraordinary degree of cloudy weather, 1 made but Few observations oi 

 this comet. They were all made in the mode described for Encke's comet, with the ex- 

 ception of that of March 11th, when the head having boon discovered only a few minutes 

 before its setting, it was brought as near as could be estimated by the eye, into the centre 

 of the field, and the circles were road off. This was done four times, when the cornel 

 disappeared behind the trees. V star of the sixth magnitude, having nearly the same 

 declination, was then observed repeatedly, in the same way. The following is a list ol 

 all tho stars used in the series. 



The places given below, in columns fifth and sixth, are corrected for refraction, parallax 

 and aberration, and the lasl two columns exhibit the corrections of the ephemeris, com- 

 puted from Mr. Walker's fourth parabolic elements.
