iMo. 417 V BooTis. — 4 m. Ptolemy and Sufi; 4^ Lalande ; 4-5 

 Argelander ; Sir W. Herschel v ~ 4 ; 4-5 Heis ; 4-2 Gould ; 4-5 Bir- 

 mingham, April 15, 1872, and 4 m., April 1, 1876. Schonfeld says: — 

 " Rothgelb stark veranderlich in selir langer Periode mit kleineren 

 Theilen von 50 bis 120 t" ; 4 m. Pranks, April 7, 1878 ; 3-91, Prit- 

 chard (1882-370). 



April 17, 1876, I found it very slightly brighter than t Bootis. 



March 6, 1877, about half a magnitude brighter than t. 



August 1, 1877, about half a mag. brighter than t. 



June 4, 1883, I estimated its mag. at 4-2. 



March 22, 1884, estimated 3-6, five steps brighter than r Bootis 

 (4-10 Pritchard) 



April 6, 1884, 3-6. 



'No. 418. 4632 B.A.C. Canes Vektatici. = Lalande 25538. — 6 m. 

 Lalande ; 8 m. Harding ; 5-6 Heis ; 5 Houzeau (1875' 13) ; 5 Pranks : 

 " splendid orange = P Xiii., 136," April 7, 1878. It is not in Btr- 

 mingham's Catalogue. 4' 94 H.P. 



Peb. 22, 1884, 1 found it about 4-9 m., and two steps brighter than 

 25 Can. Yenatici. 



No. 418a. WB Xiii., 830. Dr. Gould says this star, noted by Bessel 

 as 7 m., is now so faint as scarcely to be discernible with the opera 

 glass. Heis gives it (Xo. 134) as 6^'" " {JI. A. p. 321). It is not 

 given by Lalande or Harding. 



No. 419. 6 Apodis. — 5 m. Lacaille. The Cordoba estimates vary 

 from 5-6 to 6-6. It is a red star. 5 m. Cape Catalogue, 1873-39. 



Xo. 420. — ViKGiNis. — Xot in Lalande' s Catalogue or Harding's 

 Atlas. 



Xo. 421. — YiEGiNis. — Suspected variable by Professor C. H. P. 

 Peters, from observations at Clinton, U.S.A., in 1879 and 1880 {Ast. 

 JSfach., 2360). This star should probably be transferred to Catalogue 

 of Known Variables. 



jSTo. 422. e Centatjei.— 3 m. Lacaille ; 2-54 Sir J. Herschel ; 3-2 

 Bekrmami ; 2*2 Gould. The Cordoba estimates range from 2-2 to 

 2-7. 



ISTo. 423. a Draconis. — 3-4 Ptolemy, Sufi, Argelander, and Heis ; 

 3 m. Ulugh Beigh ; 2 m. Tycho Brahe and Hevelius ; 3 m. Groom- 

 bridge ; 3-71 Sir J. Herschel {Cape Ohs., p. 440); 3-56 Pritchard 

 (1882-712). Pigott says {Fhil. Trans.), "I am of Mr. Herschel's 

 opinion that it is highly probable that this star is variable. Bradley, 

 Plamsteed, &c., mark it of the second magnitude ; at present it is only 

 of a bright fourth. I have frequently examined it since October, 

 1782, without perceiving the least change, being constantly rather less
