GrORE — On Suspected Variable Stars. 349 



No. 274. Birmingham 211 Cancki.— 6i Lalande (17576); 6 m. 

 Chacornac; 7 to 7-5 Birmingham; 8m. Webb, March 6, 1872 My 

 observations are: — 



February 28, 1878, 7*3 m. slightly brighter than 2 stars np. 



December 21, 1878, 7im., and equal to the 2 stars np. 



November 22, 1883, 7i m., and eqtial to the 2 stars np. 



No. 275 60 {a}) Caistcei. — 5 m. Lalande and Harding ; 6 m. Heis; 

 8m. Webb; 8m. Birmingham; 6 m. Franks, January 30, 1878. 



Sir W. Herschel gives 45-60 , 50. 



February, 1877, I found 60 equal to 45 Cancri. 



February 28, 1878, same brightness. 



November 22, 1883, 60 two steps less than 45. 



No. 276. w Yeloeum = Lacaille 3638. — Grould says, "There is 

 some ground for supposing w Velorwn to fluctuate between 5"" and 

 5"" 5". 5-6 m. Cape Catalogue, 1880. 



No. 277. cr^ TJes^ Majoeis. — 5 m. Heis. A double star, 5-5, 9-5 : 

 244°-8 : 2"-7, 1876. Sadler thinks the com^s almost certainly variable, 

 5-5 probably so {Cel. Ohj., p. 404). 



No. 278. K Cancel— 4-5 Sufi; 41 Lalande; 7m. Bessel; 5-5 DM; 

 5m. Argelander and Heis; 5'6 Grould (at Albany), and 5*4 at Cordoba. 

 Suspected variable by Gould, although he includes it among his "Stand- 

 ards of Magnitudes " {V. Argentina, p. 26). Sir W. Herschel gives 

 47 (S) — 76 (k) , 45. January, 1876, I estimated it between 5 and 

 6|-m. ; November 22, 1883, k three steps brighter than 45. 5-03 H.P 



No. 279. K Pyxidis = Lacaille 3685 (Aego) - 3121BAC.— 6 m. 

 Lacaille ; 5 m. Heis ; 6-5 Behrmann ; 4, 4*5 and 5 m. Argelander. It 

 is No. 217 of Birmingham'' s Catalogue. Gould suspects variation, as 

 the Cordoba estimates vary from 4*3 to 5*1. He says, " Its colour is a 

 bright orange." 6 m. Cape Catalogue {1^1 ^-l^.) 



No. 280. Laxande 18044 - 5 Cancei = BD 31°, 1946.— 5i, 6 

 Lalande; 6-5 DM; 6 m. Birmingham, 1872; 7-1 Copeland, February 

 19, 1876; 7 m. d' Arrest, who finds a spectrum similar to a Herculis 

 and )8 Persei, and considers that a slight variability of the star is 

 probable {A.N. 2032). It is No. 218 of Birmingham's Catalogue of 

 Red Stars. 6-50 H.P. 



No. 281 tt' (81) CANCEi—7i m. Lalande ; 6 Harding; 6-7 Heis. 

 Sir "W. Herschel gives 54 , 81 81-68 and 81 , 83. February, 1877, I 

 found it more than a magnitude less than tt^ (6m. Heis), or about 7m. 

 November 22, 1883, ir'- about 7 m., and one step less than 54. 



No. 282. Lacaille 3731 Yeloeum. — 7 m. Lacaille; 6 Behrmann. 

 The Cordoba estimates vary from 6*3 to 7'1, and Gould says, "It is 

 not improbably variable,"
