ISo. 186. BiKMiNGHAM 147 MoNocEEOTis = Lalande 12481 (8 m.); 

 8 Harding; 8 m. Bessel ; 9 m. on Bremiker's chart. Birmingham's 

 Observations, 1873-1876, vary from 5-6 to 8. He says, ''Seems 

 decidedly variable." I cannot find any allusion to this star in the 

 JJranometria Argentina, although it was observed on several occasions 

 by Birmingham as 6 m. in the years 1873-1876. My own observa- 

 tions are : — March 4, 1878, 1\ m. — less than a 7 m. j? ; December 24, 

 1878, taint, about 8 m. ; February 14, 1880, about four steps less than 

 the star j!?, or 7-1 m. ; April 2, 1883, estimated 7-3 m. ; April 1, 1884, 

 faint, about 8 m. 



ITo. 187. 12 MoNocEEOTis.— 6i m. Lalande (12531); 6 Harding ; 

 6 Heis; 5 m. Argelander ; 5 m. Houzeau ; 6'0 Gould (at Albany) and 

 6-2 to 6-5 at Cordoba; 6m. Franks, December 31, 1877. It is 

 situated in the star cluster ^.. YII. 2. Gould calls it a " red star." 

 March 8, 1883, I estimated its magaitude as 5-9; March 23, 1884, 

 6-3 m. 



JN'o. 188. 0. A. 5270 Cai^is Majoeis.— 6 m. Harding rated 6 m. 

 bv Heis (No. 18), but only 8^ and 9 m. by Argelander, and 9 and 

 9i m. at Cordoba. 5.74 H.P. 



IN'o. 189. LalajS'de 12699 MojfOCEEOTis. — 7^ m. Lalande; 6*5 in 

 D. M. ; 6 m. Argelander and Heis ; 6"7 at Cordoba. Gould suspects 

 variation. I found it brighter than LL. 12788, in February 1877; 

 on March 23, 1884, 1 estimated it 6-3, two steps brighter than 16 Mo- 

 nocerotis. It is 6'04 and 5"7 in the H.P. 



]^o. 190. v^ Canis Majoeis. — ISTot va. Lcdande' s Catalogue; 6-7 Heis; 

 6-4 Gould; 6m. Cape Catalogue (1879-03). A double star, 6-5, 8: 

 260°-2 : 17".2. Smith called 6-5 "pale garnet" {Bedford Catalogue). 

 Birmingham says that Main found it " white," March 1, 1863. 



ISTo. 191. 1/2 CAifis Majoeis. — 3^, 4 Lalande; 5 Harding; 5 Heis; 

 4-75 Sir J. Herschel ; 4-1 Gould; 4 m. Caije Catalog-ue (1879-05). 

 January, 1876, I found it brighter than v^, and a little brighter than 

 e Canis Majoris. (4-5 Heis). 4-25 H.P. 



]S"o. 192. v^ Canis Majoeis. — 4|- Lalande; 6 m. Argelander and 

 Heis; 6m. Cape Catalogue (1879-06). Dr. Gould calls it "red" and 

 rates it 4-9. In January, 1876, I found it less than v-. 4-68 H.P. 



IS'o. 193. Lalande 12788 Monoceeotis. — 6|-m. Lalande; 6 Harding; 

 8 m. Piazzi. In February, 1877, I estimated it 8 m. — less than LL 

 12699, and LL 12852; January 31, 1878, 8 m. or 8-2 ; March 23, 

 1884, estimated 8^m., about 1 mag. less than LL 12852, and faint 

 with binocular in a very clear sky. 



No. 194. P.YI 174 Ltncis.— A double star 7^, 10 : 134-2 : 4"-0.
