Gore — On Stispeefed Variable Stars. 405 



JSTo. 691. f Pegasi. — 4-5 Sufi; 5 Lalande and Bessel ; 4-5 Arge- 

 lander and Heis ; 4-8 in D.M. Sir W. Herschel gives 2 (e) -23 (^). 

 13 (v) ; 4*6 Gould (at AlLany), and 4*3 at Cordoba. Gould suspects 

 variation. 4-62 Pritchard (1882-658). September 4, 1883, I estimated 

 it two steps brighter tban 55 Pegasi. 4-23 and 4-5 H.P. 



[N'o. 692. e Grtjis. — 4 m. Lacaille ; 4-5 Behrmann ; 4 m. Cape 

 Catalogue (1876"72); 3*5 Gould, who says, there is some reason to 

 suspect that it is " somewhat variable with a long period." The 

 Cordoba estimates " showed a regular increase of brightness througli 

 each stage from 3' 7 to 3*4." 



No. 693. - 69 Aqtjaeii.— 5, 5|-, and 6 Lalande (t^) (44568-70) ; 

 5 m. Harding ; 6 m. Heis ; 5*8 Gould ; 6 Franks. Gould marks it " red." 

 5-55 H.P. 



December, 1875, considerably fainter than t^ (71) Aquarii. 



September 6, 1877, I found this star equal to 74 and 77 Aquarii, 

 but less than t Aquarii (71 Fl.). 



IS'o. 694. -Aqtjakii. — A nebula discovered by Tempel, September 

 19, 1879, and suspected of variability from the fact of its having 

 escaped detection by previous observers. He describes it as very little 

 fainter than the nebula Herschel II. 744 (Nature, IS'ov. 20, 1879). 



No. 695. i Cephei. — 4-3 Ptolemy, Sufi, and Argelander ; 4 m. 

 Harding; 3-4 Heis; 3*73 Sir J. Herschel {Cape Observations, -p. MO); 

 4 m. Pranks, October 13, 1877 [private letter). Schmidt considers 

 this star to be variable with a period of 368 or 369|- days. He found 

 maxima, January 10, 1848 ; January 1, 1849; and January 15, 1850; 

 and minima on July 30, 1848; July 18, 1849; and August 7, 1850. 

 He compared the star with y, but thicks it doubtful which is the 

 variable (AN 1069); 3-61 Pritchard (1882). 362 and 3-8 H.P. 

 Sir W. Herschel found /3 - , t. 77, and 32 (t) ; 3 (•>/). 

 In December, 1876, I found l a little less than y, and slightly less 

 than t, Cephei. 



No. 696. y (22) Piscis Austealis. — 6 m. Lacaille ; 4-5 Argelander, 

 Heis, and Behrmann. The Cordoba estimates vary from 4"5 to 5"0. 

 In 1874 I found y less than /?, but brighter than S. 



No. 697. Lalande 44782-4 Piscium. — 7 and 7^- Lalande; 8 m. 

 Bessel ; 6|- Lament ; 8 in DM ; 6-7 Heis, but found by Gould much 

 below 7 m. He thinks it "not improbably variable " (Uranometria 

 Argentina, p. 40). 



No. 698. p Pegasi.— 5i 6 Lalande; 5 Harding; 5 Heis; 5-2 

 Gould; 5 Pranks, October 14, 1877, "slightly brighter than or" 

 {private letter). Sir W. Herschel found 46 (^)- 50 (p), 49 (o-) and 50-31. 



I found this star about half a magnitude brighter than o- Pegasi 

 (5 m. Heis, and 5-3 Gould) on the following dates :— October 8, 1879 ; 

 October 14, 1879 ; and three steps brighter on the following dates : —
