Mr. Bowditch on the Comet of 1811. $25 
On the 16th of October the apparent length, observed by Professor 
Farrar at Cambridge, was 143°: and if we suppose the direction to be 
opposite to the sun, the real length would exceed 50 millions of miles. 
The elements of the orbit of this comet are wholly different from 
~ any of those whose orbits have already been calculated, as may be seen 
by comparing with the tables, published in the systems of Astronomy 
_ of La Lande or Vince. The perihelion distance of this comet is so 
nearly equal to that of the distance of the earth from the sun, that were 
it not for the great inclination of the orbit and the present situation of 
the perihelion, the comet might approach towards the earth so as to be 
thirty times as near the sun. But in the present situation of the or- 
bit, the comet cannot possibly approach so near to the earth, as sever- 
al of the known comets have done.
