Gore — On Suspected Variable Stars. 395 



October 16, and October 29, 1872, and on the latter date it was nearly 

 2 magnitudes fainter than on the 16th. Schonfeld includes the star 

 in his provisionial list, and says, " Die Yerandelichkeit ist wesentlich 

 aus den Grossenschatzungen der Cataloge geschlossen, vielleicht auch 

 in Birmingham's eigenen Beobachtungen ausgesprochen. Seit April 

 21, 1874, hat sich der Stern hochstens um ein paar Stufen verandert." 

 October 7, 1879, I found this star about 6'3m. slightly less than 

 1 Delphini ; November 10, 1879, same brightness 6'3.
