GroRE — On Suspected Variable Stars. 331 



(8|-m.). It is 9 m. iu Uardinc/'s Atlas. On similar grouiids Espin 

 suspects variation in a star in Leo Minor DM 33°, 1895). {See 

 " Supplementary List.") {See Espin' s ■^' Catalogaie of tlie Magnitudes 

 of 500 Stars." — Proceedings of the Liverioool Astronomical Society, 

 1884). 



]S"o. 154. Anon Tatjui. — Found by Schmidt to vary from 8-9 to 

 11-12 (1861-1864) {Ast. Nach., 1513). 



No. 155. A. Okionis. — 4 m. Lalande; 4*05 Sir J. Herschel {Cape 

 Obs., p. 346); 3-4 Heis. Grould considers this star probably variable' 

 to the extent of more than half a magnitude ; 3'52 Pritchard (1883'040). 

 March 18, 1876, I found A equal to rj Orionis, and about half a magni- 

 tude less than t Orionis (3-4 Heis). 3'49 and 3-8 H.P. 



No. 156. Lacaille 1890 CoLTjMB^. — 6 m. Lacaille. According to 

 Gould this star, which is red, was once reported by Gilliss to be missing, 

 although it is in his Santiago Catalogue. It was also observed by 

 Piazzi, Brisbane, and Taylor. The Cordoba estimates vary from 6 "2 

 to 6"7 ( Uranometria Argentina, p. 292). 



No. 157. 42 Oeionis.— 4 m. Sufi (30th star of Orion.); 6 m. La- 

 lande (10540). Heis rated 42 and 45 together as 5-4. Gould sus- 

 pects variation in either 42 or 45, from observations at Cordoba. 

 4-60 H.P. 



No. 158. Lalande 10527 Orionis. — Eated 8 m. by Lalande, and 

 suspected by Ealb and Gould to be variable. It is a double star % 747 

 (LL 10527 and 10529). It lies closely s.p. i Orionis, and I have often 

 seen it with the naked eye in the Punjab sky in full moonlight/ 



Erom the Cordoba observations, Dr. Gould concludes thatLL 10527 

 varies between 5|- and 7^, while LL 10529 remains nearly constant 

 ( Uranometria Argentina, p. 329). The proximity of the star to t Orionis 

 renders observations difficult. March 8, 1883, I found this star, with 

 binocular, less than v Orionis, but brighter than 49 Orionis, or about 

 mag. 5-2; February 22, 1884, one step less than 49, or 5*3 m. 

 4-47 H.P. 



No. 159. Anon Oeionis. — Estimated 6-7 to 7*0 at Cordoba ; but 



by _ „ . . . , 



February 22, 1884, I estimated it 6"9 m. ; two steps less than a star 

 8./. (123 of Orion, Gould). 



No. 160, 45 Oeionis. — 7 m. Lalande (10555). Heis rated 42 and 

 45 together as 5-4. Between the two is an 8 m. star, Lalande 10547. 

 Gould suspects variation in either 42 or 45, from observations at Cor- 

 doba. 4-95 H.P.
