ppUcations of tlie method 



of Laplace gave 



the perihelioa distance, 0.3366878, and the time of passing 

 perihelion, June 27 

 between the times 



'.594973. With these numbers, the anomalies 

 of observation were calculated, and compared 



deduced from the observations 



Th 



alios be 



tween the second and third observations agreed precisely ; those 

 between the first and second differed but 40^ j so that it was 

 thought superfluous to repeat the operation. 



The remaining elements were calculated, and the whole were 

 as follows : 



• 



Perihelion distance 



0.3866878 



Time of passing the perihelion, June 37th, 7** -i' 2S^ mean time 



at New Haven, or 11'' 56' S,S^ mean time at Greenwich.

To

any considerable change in these ele- 



ments would be required by the otlier observations, the geocentric 

 latitudes and longitudes of the comet were calculated for the 



of all the observations made
