GrORE — On Suspected Variable Stars. 317 



No. 49. 7)' Hydet. — 5 and 6 m. Lacaille. The Cordoba estimates 

 vary from 6'6 to 7*5, and Dr. Gould considers it a "variable of long 

 period." 5-6 m. {Cape Catalogue, 1874-82). 



JSTo. 50. 112 PisciTJir. — 6-7 Heis; 6 m. Franks, E'ovember 23, 

 1877, included by Schonfeld in his provisional list. He says (quoting- 

 Schmidt), " 1867, hell 6 m. ; 1869, Aug. nur in Opernglase zu sehen, 

 AN 74, 1770." The Cordoba estimates vary from 6-0 to 6-4 ; March 4, 



1877, I found the star mearly 6 m., and brighter than a star??./, a 

 Piscium ; December 23, 1878, equal to a star s.p.; November 9, 

 1882, equal to the star s.p. ; September 30, 1883, 112, two steps less 

 than the star s.p. 5-84 H.P, 



No. 51. a Htdei. — 2|- m. Lacaille; 3-4 Behrmann ; 2-9 Gould; 

 3-44 Sir J. Herschel, who says " variable (?)" His estimates of mag- 

 nitude vary from 3-26 to 3-83. It is 3-2 in the Cape Catalogue 

 (1873-99). The Cordoba estimates, however, do not confirm the 

 suspicion of variation. 



No. 52. a PiscruM.— A double star 2-8, 3-9 : 324°-0 : 3"-08, 1877. 

 Suspected " variable in brightness and colour " [Ohservatory , October, 



1878, p. 186), a was rated 3-4 and 4-3 by Sufi ; 3^ by Lalande, and 

 3-4 by Argelander and Heis. Gould gives it 3-8 ; Pritchard 3-71 

 (1882-623). 3.99 H.P. 



No. 53. Lacaille 617 Htdei. — 7 m. Lacaille. Repeatedly observed 

 at Cordoba as 7f, but twice recorded in 1872 as brighter than 7-0 

 ( Uranometria Argentina, p. 242). 



No. 54. 61 Ceti.— 7i- and 6m. Lalande; 6-7 Heis; 7*3 DM. 

 Sir "W. Herschel gives 60-61, 63. Dr. Gould says the various esti- 

 mates at Cordoba indicate a fiuctuation through more than a magni- 

 tude (Z7. A., p. 313). In November, 1876, I found 61 about haK a 

 magnitude less than 60, but a little brighter than a star n.f. ; Septem- 

 ber 27, 1883, I estimated it 6*0, from comparisons with 60 Ceti and 

 LL 3889 {n.f.). 



No. 55. V FoENACis (= L 618 = LL 3864) 6 m. Lacaille ; 6^ La- 

 lande ; 5 m. Behrmann ; 4 Argelander ; 5 Heis. The Cordoba esti- 

 mates vary from 4-9 to 5*7. 



No. 56. a Aeietis. — This star, according to Gould, shows signs of 

 fluctuation in its light (Z7. A., p. 342). It was rated 3-2 by Ptolemy 

 and Sufi; twice as 2 m. and thi'ee times 3 m. by Lalande; 2-40 by 

 Sir J. Herschel; 2m. by Argelander and Heis; and 1-9 at Cordoba; 

 2-16 Pritchard (1883-084 and 1883-175). 2-04 and 2-3 H.P. 



No. 57. 55. Cassiopeia. — 6-7 Heis ; 6 m. Franks, November 29, 

 1877. With reference to this star, Houzeau says, " L'etoile 55 

 Cassiopeiae etaitpour moi bien visible et de 6 me. grandeur en 1875-10. 

 Elle est marquee seulement 8-9 dans I'Histoire celeste de Lalande, 

 p. 379." 6-08 and 5-8 H.P.
