the mean equinox of 1875.0, given, respectively, to the nearest tenth of a minute 
of time and the nearest minute of arc. 
The sixth contains the number of observations. 
The seventh contains the mean ' determined magnitude. 
The eighth contains the U. A. magnitude. 
The remaining columns contain the dates of the separate observations (month, 
« 
day, and year), and the magnitudes. 
Where there were more than three observations (6th column), the additional 
observations are given in the notes following the Catalogue. 
Vakiable Stars. 
During the progress of the -work eight variable stars have been discovered, 
including two of the Al^ol type, namely: U OpMucJii in 1881, U Ceti in 1885, 
U Aqnilce and Y Sagittani in 1886, B Canis Majoris in 1887, Y Oj)hmcM and 
W Bijdrm in 1888, and (?) Lejpork in 1891. 
In addition, there are many cases of large discordance, notably numbers 53, 
138, 384, 400, 415, 512, 514, 525, 543, 606, 609, 610, 611, 716, 757, 855, 944, 
1107, 1229, 1234, 1253, 1357, 1449, 1513, 1562, 1646, 1890, 1931, 2002, 2078, 
2219, 2231, 2285, 2499, 2506, 2542, 2580, 2582, 2610, 2632, 2641, 2668, 2670, 
2781, 2822, 2880, 2931, 2932, 3023, 3077, 3368. I think it probable that varia- 
bility will be found in some of these cases. These stars are worthy of special 
attention, but other work has prevented my systematically observing them. 
There are yet other suspicious cases, mentioned in the notes accompanyin 
the Catalogue
