COMET OF 1 889- 1896- 1 903 225 



of 1889 and 1896, but not for the appearance of 1903. It was 

 not deemed advisable nor necessary to wait until the present 

 appearance shall be over so as to include all the observations 

 of this appearance, as this would probably delay the work for 

 a year or more. 



The present paper, therefore, naturally divides itself into two 

 parts : 



1. The determination of the elements which best represent 

 the motion of the comet at the time of its discovery in 1889. 



2. Using the elements, thus determined, as a basis, the dis- 

 cussion of the action of Jupiter upon the comet in 1886, and a 

 determination of the most probable orbit previous to that dale. 

 In this part is included the discussion of the possibility of the 

 identity of this comet with that of Lexell.
