errors required to produce this discrepancy would be very 
small, we may combine both series of observations for a mean 
epoch, which will give.

separates the two stars of the close double star. Observed without artificial illu-

The mean of 12 observations taken July 9, 1823, with the 
Five-feet Equatorial, was l' 4 ^'.962, differing only o // .4i5 
from the present determination.
