raid-day at Marseilles, it had 152° 11 '.6, of right ascension and 

 25° 22'.9 of northern declination on the 19th, at 10" & 10* it had 

 154° 30'.5 of right ascension and 24° 4'.9 of northern declination. 

 M. Gambart has deduced the following parabolic elements 

 from the observations of M. Blanpain. 



Perihelium distance 0.88117 



Longitude of the Perihelmm 255.° 51' " 



Longitude of the Nucleus 107.° 46' 



Inclination of the Orbit 8.° 26' 



Heliocentric Motion, direct. 

 M. Gambart has drawn as a conclusion from his calculations, 

 that on the 24th July, this comet was removed from the earth, 

 only one twentieth part of the distance of the earth from the sun. 

 Of the comet, which appeared so suddenly early in July, a 

 mere notice cannot be necessary, as its brilliancy was sufficient 

 to announce it to every one.
