107. 1805, Discovered by Pons the 10th Nov. and observed till the 9th 
rit Dec. Its supposed identity with the comet of 1772 has given 
oceasion to many computations, ‘This identity has not been 
confirmed ; but Gauss found that the observations agree better 
with any ellipsis that has its greater semiaxis longer than 2,82, 
than with a parabola. Mon, Corr. XIU. XIV, XXVU.
