ISTo. 616. Lacaille 8385 Sagittaeii. — 7 m. Laeaille. According^ 

 to Dr. Gould, the Cordoba observations of this star are very discordant, 

 "varying through six-tenths of a unit, and strongly suggesting varia- 

 bility in its light." 



IS'o. 617. Star iv^eae Caueington 3082. — Rated 9-10 by Argelander, 

 but estimated only 11"2 m. by me, ]krarch 15, 1880. It lies closely 

 north of Carriugton 3082 (8*3 m.). This latter star is the nearest 

 conspicuous star south of the variable R Cephei. The place given in 

 the catalogue is only approximate, but the small star in question will 

 be readily found from the above description. 



No. 618. Caekes^gtox 3106 TJesje Mixoeis. — 8'8m. Carrington. It 

 lies s.f. Carrington 3082 (referred to in the last note). It is 9-4 m. in 

 Johnson'' s Catalogue (No. 140), {Radcliffe Ohs. vol. xv.), where Car- 

 rington 3082 is rated 8"4 ; but he says that in Feb., 1856, it was 

 " certainly a magnitude brighter than No. 137 (Carrington 3082), and 

 not under 7*5. " 



Sept. 13, 1879. I found this star about 0'4 m. less than Carring- 

 ton 3082, or about 8*7 (3-inch refractor). 

 March 15, 1880. I estimated it 8-8 m. 

 March 30, 1881. Estimated 8-7 m. 



No. 619. Y. Capeicoexi. — Ihm. Lalande (38839) ; 7 m. Harding ; 

 7 m. Argelander ; 6|- m. Sir J. Herschel, vrho says : — " A fine ruby 

 star. This is the finest of my ruby stars." 6 m. TTebb, Sept. 3, 1873; 

 7*5 Birmingham. In July, 1875, with 3-inch refractor, I found the 

 star only 8|- or 9 m., and fiery red; Nov., 1876, 8|-m, and much 

 fainter than a 7 m. star n.f. 4 Capricorni, colour fiery red, 3-inch 

 refractor, visible with binocular; 2nd Aug., 1877, about the same 

 magnitude. Secchi also suspected variation; and he estimated the 

 star at 7-5, July 15, 1868, deep red; 7 m. Sept., 1869. 



No. 620. - 7001 B.A.C. Ctgxi.— 6 m. B.A.C. Not in mis' Cata- 

 logue. 7 m. Franks, 1877. 



No. 621. a Pavox^is. — l^m. Lacaille; 2m. Behrmann; 2*33, Sir 

 J. Herschel, who says "Variable (?) " his estimates of magnitude vary 

 from 1-99 to 2-55. It is 2 m. in the Ca2)e Catalogue (187 o- 65), and 

 2*1 in the Uranoynetria Argentina. 



No. 622. Laiaxde 39222 AQUiLiE. — 5 and 6^ Lalande; 7i- Piazzi; 

 6 m. Ai'gelander and Heis ; 6-5 in D.M. ; 6-0 Gould (at Albany). The 

 Cordoba estimates vary from 5-8 to 6-4. 



No. 623. BiEMixGHAM 558 Delphixi. — 7, 6 and 6A- Lalande, 

 Birmingham's estimates of magnitude (1872-1876) vary from 6 m. to 

 invisibility. He says "the star is certainly variable." The Cordoba 

 estimates are 6-4, 6-6, and 6-7. Lynn states that he observed this on
