# A Voyage to Terra Australis/Volume 2/Appendix 1

APPENDIX.
APPENDIX.
No. 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.

The irregularity of this table, compared with Table VII. of the Appendix to Vol. I., arises from its having been sometimes found advisable to make use of one time keeper in preference to both,—from some stations being fixed by the survey where no rates are found,—and latterly from No. 543 having stopped. In other respects, the explanation which follows the former table will generally apply here.
