Chapter XXV: Appendix: I

ACCOUNT OF THE OBSERVATIONS BY WHICH THE LONGITUDES OF PLACES ON THE EAST AND NORTH COASTS OF TERRA AUSTRALIS HAVE BEEN SETTLED.

In the Appendix to Vol. I. a statement was made of the circumstances under which the observations for settling the longitudes of places on the South Coast were taken; as also of the method used in the calculations, and the corrections applied more than what is usual in the common practice at sea. That statement is equally applicable to the following tables for the East and North Coasts, and the explanation of their different columns is the same; a reference therefore to the former Appendix will render unnecessary any further remark on these heads.

The first observations on the East Coast were taken at Port Jackson, and the results would naturally form the first table of this Appendix; but these observations being so intimately connected with those on the South Coast that the time keepers could not receive their final corrections without them, the Port-Jackson table became an indispensable conclusion to the former series; and it is thought unnecessary to repeat it in this place.
