Motion direct. 

 There appears to be an error in the right ascensions of 

 either the 16th or 17th of May, as the comet has reached its 

 maximum of M. somewhat later ; but Mr. Taylor has found 

 them thus recorded in the Journal. 



I take this opportunity of sending you some observations 

 made by Mr. Benjamin Valtz, at Nimes, with the elements cal- 

 culated by the same gentleman from his own observations.

The last elements represent the observations of M. Valtz 

 to the nearest minute during a period of 38 days. This comet 

 has passed within ^\h of the sun's distance from the earth to- 

 wards the end of the month of March, and could have there- 

 fore been sooner discovered. 



At Geneva the comet was seen until the 2nd of June, but 

 showed only an indistinct mass of light, very pale and dif- 

 ficult to be seen ; and on account of its great faintness, which 

 could not bear any illumination of the wires, no observations 

 could be made on it. I remain,
