Comet of July, 1832. 



in other words, if this remarkable event should occur about the mid- 

 dle of October, it would take place within such a distance as to ad- 

 mit of its being observed by the unassisted sight.

Comet of July, 1832. — Eugene Bouvard has recently calculated, 

 at the observatory of Paris, the following elements of the parabolic 

 orbit of this little comet, from the observations of M. Gambart at 

 Marseilles, continued from July 19, when he discovered it, to the 

 27th of August. 



Instant of the comet's passage of the perihelion — 1832, September 

 26.028058 — mean time reckoned from midnight at Paris. 



Perihelion distance, 



Longitude of the perihelion, 



Longitude of the ascending node, 72° 26' 41.9" 



Inclination of the orbit, 43° IS 7 3.1" 



Heliocentric motion, retrograde. 

 These elements, which have been communicated to us by Eugene 

 Bouvard, will be inserted in the Connoissance des Temps for 1S35. 

 They are interesting as the first advances of this young astronomer, 

 in a career so usefully and honorably marked out by his uncle. The 

 subjoined comparison of the positions observed by M. Gambart with 

 those resulting from the elements of M. Bouvard, appear, in our view, 

 by their very small differences, to justify the highest confidence in the 

 exactness of their elements.
