Stanley, R.N. F.R.S.

The first three columns require no explanation.

The fourth (interval of days) is the elapsed time between the last day at
the first station and first day at the second.

The seventh (meridian distance in arc) is the result of the particular
measurement specified between the two places named.

The eighth (mean meridian distance from Sydney) is that deduced by a mean
value of two or more distances by the same T.K.'s, and in some instances
of ONE ONLY, in some of the principal stations connected with the survey.

The times throughout these abstracts have been determined by equal
altitudes of the sun, excepting in those instances where the contrary is
specified by A.A. The interpolations in the Rattlesnake's distances have
been calculated by Owen's method: those of the Bramble by a method of
Lieutenant Yule's.

In the Rattlesnake's distances interpolation has been employed
throughout; in the Bramble's only where an intermediate distance is
measured between two rates.

The asterisks point out the place to which the mean meridian from Sydney
refers.
