APPENDIX 2.

ABSTRACTS OF MERIDIAN DISTANCES MEASURED DURING THE VOYAGE OF H.M.S.  RATTLESNAKE, 1847 TO 1850, BY CAPTAIN OWEN STANLEY, R.N., F.R.S., AND LIEUTENANT C.B.  YULE, R.N.

The following pages contain abstracts of the meridian distances measured in H.M.  Surveying Ship Rattlesnake and her tender the Bramble, in the survey of the Inner Route through Torres Strait, the Louisiade Archipelago, and the South-east Coast of New Guinea, during the years 1847, 1848, 1849 and 1850, under the command of the late Captain Owen 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.
