G-ORE — On Suspected Variable Stars. 315 



jSTo. 31. PiscitTM. — Suspected variable by C. H. F. Peters, from 

 observations at Clinton, IT. S. A., 1879-1880. On January 5, 1880, 

 he found it 10 m, but on other occasions much fainter, and sometimes 

 invisible. Probably this star should be transferred to the list of 

 "known" variables. 



No. Sla. 8 Cassiopeia. — 3 m. Ptolemy, Sufi, and Argelander 3, 

 and 4i Lalande ; 3-2 Heis ; 3-4 Howzeau ; 2-89 Pritchard (1882-810). 

 Gemmill's observations from March, 1882, to October, 1883, vary from 

 2-7 to 3-2 {Unglish Mechanic, February 8, 1884). In October, 1876, 

 I found 8 half a magnitude less than y, and more than half a magni- 

 tude brighter than e. 2-84 and 3-0 H.P. 



!N"o. 32. Lalande 2598 Ceti. — 6J Lalande ; 7 m. Harding ; 8 m. 

 Bessel. The estimates at Cordoba vary from 6'5 to 7*8 ; and Dr. 

 Gould says ''this is certainly variable." 



No. 33. Lalande 2677 PiscniM. — 7 m. Lalande, Bessel and 7'0 in 

 the DM : 6-7 Heis ; 5*9 Gould, who suspects variation. 



ISTo. 34. Lalande 2798 Ceti. — 7 m. Lalande; 6*9 m. Gould, who 

 marks it " var. (?) " in the Zfranometria Argentina, but gives no 

 particulars. 



No. 35. 40 Cassiopeia. — 4 m. Lalande, 1789, and 6 m. 1790; 5-2 

 ia the Durchmusterung ; 4' 7 in the first Eadcliffe Catalogue ; 6 Piazzi; 

 5-6 Groombridge and Heis {Nature, December 30, 1880). Sir W. 

 Herschel gives the sequence, 42, 40, 38. 6 m. Franks, November 25, 

 1877. 5-46 H.P. 



No. 36. 3447 h Scitlptoeis = Lacaille 462 (6m.). — A double 

 star, 6, 7, 90°-6 : 3", 1887 (0. Stone), and the components are suspected 

 of variation {^Gel. Ohjects, App. iii.). Gould calls it t Sculptoris, and 

 rates it 5-9. 6 m. Cape Catalogue (1878'86). 



No. 37. Lacaixle 468 Ekidani. — 6 m. Lacaille. Believed to be 

 variable by Gould fi'om 5*9 to 6-5, " or, perhaps, even wider limits." 



No. 38. Lacaille 480 Sculptoeis. — With reference to this star, 

 Gould remarks, "This appears to be generally below 7'""0, but has 

 been three times observed as bright as 6'""9, once by Mr. Hathaway, 

 and twice by Mr. Thome." 



No. 39. 42 Cassiopeia. — Rated 6-7 by Heis, but found by me, 

 December 12, 1876, fully equal to 46 Cassiopeiae (5 m. Heis) ; Feb- 

 ruary, 1877, same brightness ; March 3, 1883, 42, 1 step less than 46, 

 and 2 steps brighter than 43, or about 5*1 m. Sir "W. Herschel found 

 42, 40, and 48-42-38. 6 m. Franks, November 25, 1877. On Sep- 

 tember 10, 1883, I estimated 42, 5-3 m. 



No. 40. Steuve 155 Piscium. — A double star 7-5, 7-9: 332°-8 : 4"-6. 

 Dembowski thought the components variable.
