No. 57. Y Cancel — Maximum observed by Sawyer, 1883, April 
17, equal in brightness to DM + 18°, 1947, or about 7*7 m. {A. N., 
2591.) 
IN'o. 58. U Cancri. — Maximum given was observed by Knott, mag. 
10-6. 
1^0. 60. S Htde^. — Maximum given was observed by Sawyer, 
mag. 8' 2. (Gould, Ast. Journal^ 155.) 
IS'o. 62 N Velorum. — Dr. Gould suspects variation in colour 
also. The period has not been well determined. {Uranometria 
Argentina^ p. 276.) 
l^'o. 63. E CAEiNiE. — Maxima were observed by Tebbutt, 1880, 
December 16 ; 1881, October 21 ; and 1882, September 2 ; and minima, 
1880, July 5 ; 1881, June 8 ; 1882, March 27 ; and 1883, February 7. 
ITo. 64. E Leonis Minoeis. — Duner finds a spectrum of the third 
type, with very large and dark bands, even in the blue. Maxima 
were observed by Schmidt, 1882, January 26*0 (mag. 6*8) ; and 1883, 
June 29 (mag. 7). 
iN'o. 65. E Leonis. — Eecently observed maxima, are as follows : — 
1884, February 5, 6*7 mag. Sawyer. 
1884, February 13, 6-6 ,, Baxendell. 
j 1884, December 20, 6-0 ,, Baxendell. 
( 1884, December 24, 5-3 ,, Sawyer. 
A minimum of 9 m. was observed by Schmidt, 1882, JS'ovember 6, 
and that given in the Catalogue by Espin. 
Treating the observed maxima from 1865, February 27, to 1884, 
December 20, by the method of least squares, I find the following 
elements : — 
Epoch, max. = 1874, August 19-36 + 313*999 E. 
Espin finds that the bright bands of the spectrum are brighter as 
the star is on the increase, and fainter as it decreases. 
ITo. Q&a. — Leonis. — A Durchmusterung star, missed by Becker, but 
afterwards found, 1882, April 4, as 8'6 m. Chandler found the star 
invisible, with 6^-inch refractor, from end of February to middle of
