No. 256.-Cancri. — See Astronomische Nachrichten, No. 2434. 



No. 257. \lr Cais^cri. — 6 m. Lalande ; Sir W. Herschel gives i//^ , w^ 

 and 6 (;)()- 14 (i/f-) , 11; 6 m. Argelander ; 6-5 Heis; 6ra. Houzeau 

 (1875"24), who says, "L'etoile xp-z Cancri, estimee par Lalande de la 

 4nie. grandeur, dans la Conaissance des temps de 1810, figure senle- 

 ment dans mes observations comme un astre du 6 me. ordre." Franks 

 estimated it 6 m. January 31, 1878, and says, " Certainly variable — 

 fine pale yeUow." 5-78 H.P. 



I found the star 6 m., April 7, 1875 ; April 1, 1884, 1 estimated it 

 5-9. 



No. 258. Steuve1198B:tde^.— Adoublestar, 8, 8-2: 157°-5: 33". 

 Struve suspected the components of variation ( Celestial Oljects, p. 325). 

 It seems to be Lalande 16011-12, rated 9^ and 9 m. 



No. 259. Lacaille 3197 Ptjppis. — 6 m. Lacaille ; 5-6 Behrmann; 

 Gould says, " I suspect this star of variability between the approxi- 

 mate limits 5-1'" and 5-8°." 



No. 260. Lacaille 3236 Yeloeitm.— 6-0 m. Gould (''red"); 5-6 

 Cape Catalogue (1880). Stone says, " This star may be variable. La- 

 caille calls it a 7 magnitude star." 



No. 261. 30 MoiiTocEEOXis = C Htdej- (Gould). — 3 m. Ptolemy and 

 Sufi; 4m. Lalande (16559-60); 4-3 m. Argelander and Heis; 4-5 

 Houzeau (1875-18) ; 3*8 Gould; 5 m. Franks, January 30, 1878 ; 3-63 

 Pritchard (1882-971). This star is placed in Hydra in Lalande^ s Cata- 

 logue, and is called C Hydrge in the Uranometria Argentina. It is 

 4-5 m. in the Cape Catalogue (1879*09). 



March 4, 1884, I estimated it 3-9, three steps less than S Hydrse; 

 April 1, 3-8. 



No. 262. Lalak'de 16615 Puppis. — 5|-m. Lalande. Gould says it 

 " appears to vary from b\ m. to below 6 m., yet its colour may have in- 

 fluenced the estimates to some extent." 5-76 H.P. 



No. 263. ySYoLAi^Tis. — 4 m. and 5 m. Lalande; 4-57 Sir J. Herschel ; 

 6m. Gilliss; 4-5 Behrmann; 4-2 Ellery (1869). The Cordoba esti- 

 mates vary from 3-6 to 4-4 {TJ.A., p. 249). 



No. 264. Lacaille 3344 (Aego). — 7 m. Lacaille; not in Harding^ s 

 Atlas; 6m. Behrmann (1 Mali); not in Seis's Catalogue. The Cor- 

 doba estimates fluctuate from 6-9 to 7*7 ; and Gould says, " The star 

 is probably variable between the limits 6™ and 8"." 7 m. in Cape Cata- 

 logue (1878-23). 6-36 H.P. 



No. 265. 6 Cancel — A star with a distant companion, 5\, 9 : 59°-5 

 60"'7 (1880). According to Chambers, Knott suggests variation, as 

 he found the companion only 12 m., whereas Sir J. Herschel and 

 Smyth agreed in calling it 9.
