jNo. 352. 7) Ceateeis. — 4-3 Ptolemy ; 5-6 Sufi ; 4 m. Ulugh 

 Beigh, Tycho Brahe, and Hevelius ; 4, 4|- Lalande ; 6 m. Heis and 

 Argelander; 5-4 Gould; 6-7 Houzeau, "var?" (1875-25); 5m. 

 Franks "= e and bright white," March 29, 1878 ; 5-6 Cape Catalogue 

 (1879-24). In April, 1876, I estimated the difference between ^ 

 (5 m. Heis) and t] to be rather less than one magnitude ; April 15, 

 1877, 7/ nearly equal ^. The star seems certainly variable. 5-01 H.P. 



No. 353. 7 (b) YiEGiNis. — Marked 4 m., and ''variable" in 

 Dun's Atlas (Plammarion's edition) ; 5^, 6 Lalande (22571-2) ; 6 

 Argelander; 6-5 Heis; 5-8 Gould; 5^ Pranks, March 29, 1878 

 (private letter). April 6, 1883, I found 7 Yirginis more than half a 

 magnitude brighter than 10, and three steps brighter than 11 Yirginis ; 

 10 seems rather below than above 6 m.; April 7, 1883, the above 

 observation confirmed — 10 not above 6 m. 7 is 5*22 and 5-7 in H.P. 



No. 354. 31 Ceateeis.— 6 and 4i Lalande (22591-2); 6 Heis; 

 5-5 Gould (No. 4 of Corvus) ; 5 Pranks = 77, March 29, 1878; 5-6 

 Cape Catalogue (1879-23). In April, 1875, I found this star about = 

 7] Crateris ; not equal to ^ (5 m.). In April, 1876, it seemed very 

 nearly equal to ^. 5-10 H.P. 



No. 355. Lacaiile 5013 Htde^. — 7 m. Lacaille ; 6, 7, and 6|- 

 Yarnall ; 6-7 Cape Catalogue [IS7 8-29). Dr. Gould says "the varia- 

 bility of this star seems more than probable, our eleven estimates 

 ranging from 5-9 to 6-6." 



No. 356. e CoRvi. — 3 m. Ptolemy and Sufi. Eated 6 times as 

 4 m., and once 3J by Lalande ; 4 Harding ; 3 Argelander, Heis, and 

 Behrmann ; 3-3 at Coi'doba ; 3-28, Sir J. Pierschel (or very slightly 

 less than 8). Sir W. HerscheU gives /3, e, S. 3-14 H.P. 



Prom the Cordoba observations. Dr. Gould concludes that all four 

 stars, /3, y, S, and e Corvi are variable " within moderate limits " 

 {Uranometria Argentina, p. 315). The estimates for e vary from 3-06 

 to 3-51. 



No. 357. 3 CoEvi.— 6 m. Lalande (22850); 6 Harding; 6-7 Heis ; 

 6 Behrmann ; 5-8 in the Uranometria Argentina. Sir W. Herschel 

 gives 5 (C) — 3 — , 6 ; 6-5, Cape Catalogue. 5-25 H.P. 



No. 358.— YiRGii^is. = DM 0°, 2910. Pound to be variable by Prof. 

 Harrington of Ann Arbor University, U. S. A., in 1881. It reached a 

 minimum on May 22-3, when it was 8-7m. The star is not in 

 Lalande' s Catalogue, nor in Harding's Atlas. The position given by 

 the discoverer places the star about l^°j?the star rj Yirginis. The 

 nearest star in Harding's Atlas is an 8m, about 20' south.
