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,
