"successively" (" successivernent") . Such an expression 

 might almost lead us to infer a series of colours like those 

 of the Tychonian Star before spoken of; but Sir John 

 Herschel (I believe more correctly) regards it us a 

 description of coloured scintillation (Outlines, p. 563), as 

 Arago has interpreted an almost similar expression of 

 Kepler's, relatively to the new star, in 1604, in Ophiuchus

i. The appearance of this star, which is said to have
