magnitude by Harding and Hencke, I suspected this star of variation. 

 January 22, 1877, when I found it reddish, and nearly half a mag- 

 nitude brighter than Lalande 14105, which lies closely south of it; 

 January 31, 1878, a little less than LL 14105 ; February 25, 1880, 

 one step brighter than LL 14105; January 30, 1883, one step less 

 than LL 14105; March 3, 1883, two steps less than LL 14105; 

 February 22, 1884, two steps less than LL 14105. This star seems 

 certainly variable to a small extent. Gould gives LL 14105 

 as 6-9. 



]S"o. 212. 18 Heis Ltncis = Lalande 14028 (5 m.)— 5-8 Arge- 

 lander, 5-2 in DM; 6-7 Heis; 5-01 Pierce, who says {Harvard 

 Annals, vol. ix.), " Heis makes this star 6*3, and I, 5*0. Argelander 

 makes it equal to 26 Lyncis; Heis makes it 0"5 fainter; the D M., 

 0-2 brighter; and I, 0-4 brighter. Argelander makes it equal to 16 

 Heis Lyncis; Heis makes it 0-5 fainter; the D M., 0'3 brighter ; and 

 I, 0-5 brighter. April 8, 1876, it seems not to have changed since my 

 measures." 4*77 and 4-9 H.P.

 Argelander; 6-5 Heis ; 6 m. Behrmann; 5 '4 Gould. Sir "W. Herschel 

 found 28-27 , 26. In 1874, 1875, and 1876, I found it about 5|-m., 

 and much inferior to 28 ; February, 1877, slightly brighter than 29.

 by Piazzi. In January, 1877, I found this star only 9 m.

1^0.216. Steuve 1058 Canis Minohis. — A double star 8^,11: 

 281° : 22"-32, Burnham, who measured it in 1879 and 1881, but failed 

 to see the companion in 1874-5 and 1878 ; Dembowski could not find 

 it in 1865.

 Beigh ; 4 m. Tycho Brahe andHevelius ; 5 and 4 Lalande ; 4-3 Arge- 

 lander; 4 m. Heis (8 = 3-4 Argelander and Heis). Sir "W. Herschel 

 found 54 (A) ; 55 (8), and says, " 54 seems to be increasing. There is 

 an interval of 9 months between the two observations of my catalogue. 

 Mr. Bode supposes the star to be changeable, ^qb Astronomisclie Jahr-

Franks found X = S, both 4 m., January 28, 1878. 



January 18, 1876, I found A almost exactly equal to 8 (both small

October 6, 1883, A = 8.
