PafTage of the perihelion June 1801 



The difl'erencc of the three parabolas calculated by Oriani, 



Mr. , and nivfelf, none of which reprefent all the 



obfcrvations, confirm Hill more that the motion of this ftar 

 cannot indeed be rcprefented in a parabolic arc, as I have 

 faid in my preceding memoir. 



The fame perfon who calculated the fccond parabola tried 

 lo make the obfervalions agree with a circle. His elements 

 are : 



liadius - - - 



Kpoch iSoi 



e - 



Inclination 



Sidereal revolution - - 



In this circle the errors in excels amount to 2' 30'^, and 

 thole in defert to as much. 



Burckhardt calculated in an ellipfe, and found :

Eccentricity _ _ - o'0364 



Log. of the greater fcmi-axis - 0'4io6586 



Sidereal revolution - - years 4'i3 



In this ellipfis the longitudes and latitudes of five obferva- 

 lions arc repiefenttd pretty well, there being onlv the differ- 

 ence of a few feconds between calculation and obfervation. 



'i'lie aftronomer who calculated the parabola and. circle 

 above mentioned, and whole name I was not able to make 

 out, in the few leaves prniled in German with wlwch Oriani 

 favoured me, fulpedted that there might have been lonie error 

 in the copy (jf my oblcrvations tranfinitted to him. This 

 was really the cafe in the full ; but 1 afterwards fcnt another 

 correitea copv, as well as to Lalande, Oriani, and Bode, 

 all correfpondlng txadlly with that on wliich 1 founded niy 

 own calculations. 



However, that my exertions may correfpond with the in- 



tcrell generally taken in luy difcoverv, whatever the rcl'ult
