system almost grazing the sun’s surface in perihelion, and revoly- _ 
ing in less than thirty-seven years? I confess I feel a difficulty — 
in admitting it, notwithstanding the above extraordinary resem- 
blance of orbits.” It was also stated in the Observatory that, from 
rough places on February 10th, 13th, and 15th, Mr. Hind had — 
previously found elements somewhat different from those which 
communicated. Both sets differed in toto from Mr. Finlay’. e 
The members of the Royal Society of N.S.W. will not fail to 
perceive the utter dissimilarity subsisting between the results 
given by Mr. Hind and Mr. Finlay, but this is not all, for now the — 
Astronomische Nachrichten has come to hand, bringing more 
determinations of the orbit, varying as much from one another as 
those computed by the two astronomers already referred to. The 
following approximate determinations have appeared in that 
periodical up to April 8th, the latest date received :— a4

The elements given by M. Liais, Director of the Observa 
at Rio Janeiro, somewhat resemble those arrived at by ! 
without interest to our Society. In the Herald of the 2
