Additions to the Catalogue of Stars which have Changed their Colors. 



BY JACOB ENNIS. 



I Beg leave to add the following continuation to the Catalogue of six stars 

 which have changed their colors, recently presented as a verbal communication : 



7. Procyon. In 1850 Humboldt classed Prosyon among the yellow stars : 

 Cosmos, Vol. 3, p. 182. In a verbal communication to this Academy, Feb. 

 17th, 1863, I announced that this star is now very decidedly blue ; and in this 

 all to whom I have referred the color agree without the least hesitation. 



8. Rigel. This star is classed among the white stars by Donati, in aMemoir 

 dated August, 1860, and published in the Annals of the Museum at Florence 

 in 1862. It is now decidedly blue. During the past two months it has been 

 observed by myself and some friends to be one of the most deeply-colored of 

 all the stars now visible in this latitude. 



9. Alpha Lyra?, or Ve fa a. Donati, in the MemoiT just named, classes Vega 

 among the white stars. Humboldt, in 1850, Cosmos, Vol. 3, p. 183, says, 

 "the light of Alpha Lyrse is bluish." To myself it now appears pale blue, 

 very much like Gapella. 



10. Castor. Donati, in 1860, classed Castor among the yellow stars. Hum- 

 bsldt, in 1850,. says-, "Castor is a greenish star." Cosmos, Vol. 3, p. 177. 

 It appears to me greenish now-,. March, 1863. 



There is a close cluster of more than a hundred stars, known as Kappa 



[Mar.
