Some of the discordances in the angles are very large, but on exa- 

 mination it will be seen that those marked with an asterisk are hope- 

 lessly discordant, and it would evidently be quite impossible to find 

 any orbit which would satisfy these contradictory measures, and at 

 the same time represent the other angles which are fairly accordant. 

 In the earlier and later measures, the discordances cannot be con- 

 sidered very great, if the difficult character of the star is taken into 

 consideration.
