1^0. 145. B.A.C. 1661 Oeio^-is (8 m.)— Baily says, "Taylor con- 

 siders tlie magnitude of this star to be variable." It is Lalande 10052 

 (8), and lies closely p 23 Orionis, ISTovember 24, 1878, I found it 

 small with binocular, about 8 m.; March 6, 1883, very small with 

 binocular — less than 8 m. 



!N"o. 146. Laxande 10159 Oeioot:s. — A faint and close companion to 

 this star was discovered by Bumham, who suspects the bright star of 

 variation, as it is not found in the catalogues of Bode, B.A.C, Schjellerup, 

 Weisse, Tarnall, Eumker, or Lamont. It is 8 m. in Lalande' s Catalogue, 

 but was rated 6Jm.byBurnham {Memoirs R. A. S., vol. xliv., p. 178). It 

 is not in the TJranometria Argentina. Near 77, sf. March 4, 1883, I 

 found it very small and barely visible with the binocular. 



1^0. 147. y Oeiokts. — 2 m. Sufi, Lalande, Argelander, and Heis ; 

 2*10 Sir J. Herschel, who says "Yariable (?)" His estimates of magni- 

 tude vary from 1"77 to 2"42. It was rated 1-7 m. at Cordoba, and Dr. 

 Gouldmarksit '' var. (?)" Pritchard gives 1-79 (1882-073). 1-86 H.P. 



1^0. 148. ^ Lepoeis. — 3-4 Sufi; 3 m. Lalande; 3-4 Argelander 

 and Heis ; 3 m. Behrmann ; 4 m. Franks, December 12, 1877; 3-35 

 Sir J. Herschel, who says "probably variable." His estimates of 

 magnitude vary from 2-97 to 3-72. Sir "W. Herschel found /5 less 

 than a, but slightly brighter than /a Leporis. The Cordoba estimates 

 vary only from 2-8 to 3*0. 3-03 H.P. 



December 6, 1875, I found y8 and a Leporis nearly equal, perhaps a 

 very slightly the brighter ; March 17, 1876, a and /? exactly equal, 

 and about 3 m. ; January 22, 1877, a Leporis slightly brighter thanyS. 



jSTo. 149. 1706 B.A.C. Ca:o:lopabdaijs {Comptes Rendus, vol. Hii., 

 p. 479). — ISot in Heis' Catalogue. It seems to be jS'o. 966 of Groom- 

 hridge^s Catalogue (om.) February 24, 1884, I estimated it 6'7 m. — 

 two steps less than 1619 B.A.C. 



IvV 151. 119 Taou.— 5m. Sufi; S^ Lalande (10367); 4-4 Arge- 

 lander ; 5 m. Heis ; 5'5 Birmingham, orange. I found it very reddish 

 with binocular, November 21, 1878; January 31, 1884, I estimated it 

 4-5 (yitTauri = 4-6) and reddish. 4-57 and 4-9 H.P. 



No. 152. 1727 B.A.C. ArEie^.— In the notes to the B.A.C, Baily 

 remarks, " Taylor considers this star to be variable." It is Lalande 

 10357 (7 m.); 7 m. Harding; closely «/x AurigEe. October 30, 1878, 

 I found this star equal to Lalande 10419; March 31, 1884, estimated 

 6-8 m., three steps brighter than LL 10419. 



No. 153. Durclunusterung 45°, 1222 Atjeig^. — Estimated 8-6m. 

 by Espin from a photograph, March 10, 1884, but not found by him 

 on a photographic plate taken a few nights later. The star is 7'5 m. 

 in the Durchmusterung , and seems to be identical with Lalande 10355
