AT THE OBSERVATORY AT PARAMATTA. 



63 



Positions of the Comet, deduced from the above Observations. 



Elements. 



For the calculation of the elements I choose the Observations of the 2nd and 

 30th October and 20th December. From the apparent places of the fixed 

 stars I deduce those of the Comet, and calculate thence its apparent latitudes 

 and longitudes. 



These I reduce to mean places for Nutation and Parallax found by approxi- 

 mated Distances of the Comet, and to the Times I apply the reduction for 

 Aberration. I have then, proceeding according to Dr. Olber's method.
