GrORE — On Suspected Variable 8fars. 321 



N'o. 80. ^Ekidani. — 3in. Lacaille ; 3-4 Behrmarm ; 2*6 Gould. 

 A double star, 5,6: 81°-5 : 8"-68 (Sir J. Herschel). The magnitudes of 

 the components seemed to me in the Punjab (1875) much underrated; 

 more like 4 and 5, or 3w and 4^. As a single star I found it about 

 3 m., Dec. 1876, and considerably brighter than 12 Eridani. 



Gould thinks that one of the components is probably variable to 

 some extent. Sir J. Herschel estimated Eridani 3' 73, and r) Canis 

 Majoris 2"85, or the former 0-88 /«m!;er than the latter. Dr. Gould, 

 on the contrary, estimates Eridani 0-3 m. hrigMer than iq Canis 

 Majoris, which gives further reason for suspecting variation. 



1^0. 81. 93 Ceti.— 7 and 6 m. Lalande (5617-18); 6-7 Heis; 6-4 

 Gould. Closely n of a, with which it forms a fine open pair. Smyth 

 called 93, 5^ m. 



No. 82. p2 Eridani.— A double star, 6,9: 86°-6 : 2"-26, discovered 

 by Burnham, who suspects the companion of variation. 



No. 83. ^Peesei (Comes). — The well-known companion to Algol, 

 discovered by Schroter (1787), who suspected variation. Sadler con- 

 siders it variable from 10 m. to 14 m. in some short period. A writer 

 in Nature (Eeb. 20, 1879) states that he failed to see any trace of the 

 star on several fine nights in the early part of 1874, using a 7-inch re- 

 fractor ; but on Sept. 9 of the same year, he saw the companion very 

 distinctly with the same instrument. It was measured by Talmage at 

 the Leyton Observatory, Oct. 2, 1874 (194°-4 , 79"-02 ; mag. 11-12), 

 and by Burnham 1878-6: 192°-4: 81"-86. There are three other 

 fainter companions. 



No. 84. 12 Eeidani.— 3m. Lalande (5986); 3i Lacaille (1000); 

 3-4 Heis; 3-6 Gould (a Fornacis). It is a double star 3 , 8 : 316°: 

 2"-4 (0. Stone, 1877), and 3 is suspected of variation. 3-77 H.P. 



No. 85. ^Aeietis. — 4 m. Sufi; 5 Lalande; 6 Bessel ; 4*5 in DM; 

 4-5 Argelander; 5-4 Heis ; 4-7 Gould (at Albany), and 5-2 at Cor- 

 doba; 4-78 Pritchard (1882-704). Gould suspects variation, although 

 he includes the star among his Standards of Magnitudes ( U. A., p. 22). 

 4-93 H.P. 



Oct. 1875, I rated it 5 m. and equal to e Arietis. 

 Eeb. 1877, ^ a little less than e Arietis. 

 March 3, 1883, I 2 steps fainter than e Arietis. 



No. 86. k1 Ceti = 96 EL— 5^ and 6 m. Lalande ; 5 Heis (k-= 6) ; 5 

 Houzeau {K^ = &m.); 5-1 Gould (k^ (97) = 6-2). Franks found it about 

 6 m., and very slightly brighter than k- (Nov. 1877) "pale yellow." 

 Nov. 16, 1876, I found k^ nearly 1 magnitude brighter than k^, and 

 about = 94 Ceti ; Jan. 9, 1882, about = 95 Ceti, but less than 94; 4 

 March, 1883, k^ 2 steps brighter than 94, and k^ 3 steps less than 95.
