Considering the nature of the observations, and the 
limited number of minima and maxima compared, the near 
agreement between the two sets of results may be regarded 
as satisfactory. 
The mean magnitude of the variable in its 
Principal minimum is 9 ‘75 
First maximum 8'55 
Second minimum 9 '08 
Second maximum...... 8*68 
An examination of the columns of magnitudes shows that 
considerable irregularities in the light of the star take place 
in both minima, the range of variation at the principal 
minimum being 1*2 mag., and at the secondary minimum 
0’8 mag. The range of variation at both maxima is 0*7, the 
highest magnitude at the first maximum having been 8 ’3 
and the lowest 9*0; while at the second maximum the 
respective magnitudes were 8 '4 and 9T. 
Grouping the magnitudes at each minimum into three 
groups, and taking the means, we have the following 
results : —
