flation in March 1782, they produce an angular motion, which 

 differs confiderably from what appears by interpolation, mow- 

 ing that the mean diftance is confiderably too great. 



IT refults from this invefligation, that the elements of the 

 orbit are contained between thefe extremes, and are probably 

 much nearer to the firft fet. A confiderable time mufl elapfe 

 before they can be determined with accuracy, from obfervations 

 made fince March 1781. But the probability that MAYER ob- 

 ferved the Planet is fo great, that I am decidedly of opinion 

 that it is the fame with No. 964. of his catalogue. If ihis be 

 granted, we can obtain the elements with all the accuracy that 

 is attained in the other Planets : For the place of MAYER'S Star 

 is within fix degrees of tne Aphelion, as determined by the firft 

 fet of elements, and all the erfec~ls of its excentricity are nearly 

 accumulated in 1781 ; and are therefore moft eafily deduced 

 from the obfervations. I mall therefore fubjoin another fet of 

 elements accommodated to this fuppofition ; they were formedb y 

 me about two years ago in the ufual way, by repeated trial, till 

 the refult mould agree with MAYER'S obfervations, and with 

 all the others which I had then collected. I have not found 

 any reafon fince that time to make any change, unlefs perhaps 

 the inclination of the orbit may be increafed about 10".
