'Bo. 187 J. — Phcenicis. — Pound to be variable at Cordoba during 
ibhe course of the observations for the Cordoha Zone Catalogue. 
189. R CASsioPEiJi:.— Schonfeld's formula (max. = 1866-4 - 18-9 
+ 425'^-9E - 0'^'40 E^) does not represent observations in recent years. 
The following maxima have been observed : —

Treating the above by the method of least squares, I find the fol- 
lowing provisional elements : —

^^0. 190. U Cassiopeia. — Observations of this star are much re- 
quired. 
IN'OTES TO PROVISIONAL LIST. 
Bo. 1. PisciuM. — Announced as variable by Borelly in 1885 [Bul- 
'etin Asfronomique, torn, ii., pp. 61-63). My observations, September 
GO December, 1886, show a star 8^-9 m. close to Borelly's position. 
Bo. 2. Lalande 2598 Ceti. — Dr. Gould says, " this is certainly 
variable." The Cordoba estimates vary from 6*5 to 7*8. 
Bo. 3. 100 Piscium:. — Announced as variable by Borelly in 1885. 
M.J observations from September, 1885, to December, 1886, show a 
small variation of about 0-3 m. Observations by Mark wick, November, 
1886, to January, 1887, vary from 7*4 to 7*8. It is a double star 
S 136, 6-9, 7*8 : 79°'2 : 16"'4, and has a considerable proper motion. 
Bo. 4. Lalakde 7172 Tauei. — The Cordoba estimates of this star 
7ary from 6-8 to 7-9, and the star is probably variable. In a few 
)bservations in November and December, 1884, and February and 
N"ovember, 1885, I found it 8 to 8-2 m. Markwick estimated it 7'8 m 
m January 12, 1887, and 7*4 on February 12.
