GrORE — On Suspected Variable Stars. 319 



No. 65. Laxande 4831 Ceti. — 6|-Lalande; 7 Bessel; 6 Argelander 

 Heis and Gould, and 5-6 at Cordoba. Dr. Gould suspects variation. 

 The star is not in the Cape Catalogue (1880). 



ISTo. 66. Lalaistde 4864-5 Peesei. — 7^ and 9 m. Lalande ; 8 m. 

 Harding; 6-7 Heis; 6*7 in DM. I^ot given by Houzeau. 



Jan. 7, 1882. From comparisons with a star (6-7 Heis) south of 

 6 Persei, I estimated the magnitude of Lalande 4864 as 6-5 m. : — 

 March 6, 1882. LL 4864 about 6-5 m. 

 April 8, 1883. Estimated 6-6 m. 

 October 3, 1883. Estimated 6-2 m. 



JS'o. 67. 85 Ceti. — 6|- Lalande (5006) ; 8 m. Bessel ; 6 m. Harding 

 and Heis; 6-5 Gould; 6m. Franks, November 28, 1877. Dr. Gould 

 suspects variation, although it is included among his Standards of Mag- 

 nitude ( W.A., p. 22). This star is included in Aries, in Lalande's 

 Catalogue. 6-26 and 6*1 H.P. 



No. 68. 38 Arietis.— 6m. Lalande (5075); 5 Harding; 5-2 in 

 DM ; 5 m. Ai'gelander and Heis ; Sir W. Herschel 4*1 (Peirce's reduc- 

 tions) ; 5-4 Gould; 5 Franks (i mag. > 31), November 29, 1877. 

 5-20 H.P. 



November 24, 1878, I found 38 brighter than 31 Arietis, but less 

 than X Ceti; October 14, 1879, 38 brighter than 31, but less than X 

 Ceti; November 6, 1882, 38 about 5 steps brighter than 31, or about 

 5-2. 



No. 69. Lacaille 893 .Hoeologii. — 5 and 6 m. Lacaille ; 6-5 Behr- 

 mann; 5-8 Ellery (1870); 6-4 to 6-7 at Cordoba. Gould remarks, 

 " If it be variable, as seems probable, its minimum must have occurred 

 in 1872. The various estimates may be reconciled by supposing a 

 period of somewhat more than 3 years, and a variation of the magni- 

 tude from 5-8 to 6-7 " {ZTranometria Argentina, p. 264). 



No. 70. TT Akietis.— A triple star, 5, 8-5, 11 : 121°-6, 109°-9: 3"-l, 

 25". The 11m. comes seems to be variable, as Sir W. Herschel found 

 it brighter than the 8'5 companion, whereas Webb in 1871 rated them 

 9-5 and 13. So Sadler, 1874. Franks found 11 more like 13 or 14 in 

 1876. {Cel. Obj., p. 235). 



No. 71. 17 Peesei.— 5 m. Lalande (5242); 5 Heis; 5 Franks (>21 

 or 24), Nov. 29, 1877. In Pierce's reductions of Sir W. Herschel's es- 

 timates the stars 17, 21, and 24 Persei are rated equal, each = 4-9. My 

 observations are : — Nov. 21, 1876, 17 very slightly brighter than 24 ; 

 Nov. 24, 1878, 17 a little brighter than 24, but less than 16; Oct. 6, 

 1879, about the same ; Sept. 13, '82 about the same ; March 4, 1883, 

 17 three steps brighter than 24, and four steps brighter than 21 ; Sept. 

 27, 1883, 17 three steps brighter than 24; Dec. 6, 1883, 17 one 

 step brighter than 24. 4*80 H.P.
