1^0. 291. 10 Leonis {= 1 Heis Sextantis = LL 18893).— 5 m. La- 

 land e ; 6 m. Heis; 5-8 D.M. Sir W. Hersctel giTes 10,5 (^) ; 5-4 

 Gould, "vrho suspects variation, although, included by him in his 

 " Standards of Magnitude " ( IT. A. p. 27) ; February 22, 1884, I esti- 

 mated it 5-4 m. 4-98 and 5-7 H.P. 



No. 292. t (35) Htde^ ; 3i, 4 Lalande ; 4 and 5 m. Harding ; 4-39 

 Sir J. Herschel; 4-9 Johnson (1857); 4 m. Heis. The Cordoba 

 estimates are 3'7 to 4-3 {Uranometria Argentina, p. 298); March 7, 



1884, I estimated it at 3'7, one step brighter than B Hydrse. 



No. 293. K Htdili:. — Not mentioned by Sufi ; 4 m. Tycho Brahe 

 and Hevelius ; 4 m. and 6 m. Lalande ; 4 Harding ; 5 Heis ; 5*4 Gould; 

 b\ Franks, March 2, 1878. 4-94 H.P. My observations are : — 



April 25, 1875, k a little fainter than v^ Hydrse. 



March 28, 1876, k more than half a mag. fainter than v^. 



February 11, 1877, k more than half a magnitude fainter than v^. 



February 16, 1877, k nearly one magnitude less than v^. 



April 7, 1883, k considerably less than v" — nearly 1 magnitude. 



No. 294. Laxa?7DE 19034 Htde^. — 41 Lalande. Not given by 

 d'Agelet or Piazzi ; 6 m. Argelander, March 6, 1850; 4 m. February 

 16, 1851, and 5 m. March 8, 1852; 5 m. Heis, Houzeau, and Behr- 

 mann ; 5-2 Gould. 4*62 H.P. 



May 1, 1877, I estimated it 4i m. ; April 24, 1878, I found it the 

 brightest star in the immediate vicinity. 



No. 295. i/f Leonis. — 6 m. Sufi, Ulugh Beigh, and Argelander; 

 5 m Tycho Brahe and Hevelius ; 6 and 6* Lalande (19081-3). Sii- W. 

 Herschel gives i/^-7, and 1/^,8; 6 m. Heis; 5 and "Yar" Houzeau; 

 (1875-25); 6 m Franks, March 4, 1878. Smyth {Bedford Catalogue, 

 p. 229) gives its magnitude as 6, assumed from Piazzi, but says it was 

 " very bright for its rate " at the time of his observations. He adds, 

 " They say it once disappeared altogether, after having been noticed 

 by Montanari in 1667 ; and that Maraldi saw it again very small in 

 1691." 



January 25, 1877, I observed i/^ a little less than v Leonis (5-6 

 Heis). 



April 24, 1878. i/^ brighter than 7, 11, and 23 Leonis, and the 

 brightest star in its immediate vicinity. 



February 21, 1884. Estimated 6-0 — a little brighter than 3 Leonis- 



No. 296. 16 LeoxisMixoeis.— 6im. Lalande (19226-7); 6 Harding; 

 5 and 7-8 d'Agelet ; 8 Piazzi; 7 m. Bessel and DM. Not in ^m's 

 Catalogue, nor in Argelander^ s Uranometria; 5-6 Houzeau (1875'24); 

 7 Franks, "deep red," March 10, 1878. 6-64 H.P.
