The following was also received today : Smithsonian telegram Swift telegraphs Lohse's coniet discovered by me October I o identical with

comet third eighteen hundred sixty nine. ) A comparison of the above approximate elements with those computed by Professor Hruhns for Comet 111

18% renders an identity in the highest degree probable, especially as the descriptions of that object accord with what is now visible. Kn/ph C'ol)elnn~f.

Direct. The argumcnt is striking. if it is considered that

one of the positions used by me (Oct. 2 1 ) was given only to the nearest iiiinute of arc, and the other two (Oct. 25 and Oct. 28) art' not yet definitively reduced.

1869, it is worthy of note that he remarked that a comparison with the observations at Leipsic indicated a variation from a parabolic orbit.
