Early edition of this very large and rare hydrographic chart of Cape Naturalist to King George Sound, with detailed inset of Geographe Bay and a blank inset which in later issues had either Busselton Harbour or Koobanah Bay, added. Surveyed by Staff Commander W.E. Archdeacon, R.N. assisted by Navigating Lieutenant William Tooker R.N. 1876-80. With two coastal profiles at bottom showing Cape Leeuwin and Chatham Island. First issued 2nd September 1878, large corrections April 1883 and minor corrections XI-1896.

The regular updating of Hydrographic charts by the Hydrographic Office was to ensure that commanders of ships, pilots and other mariners were able to have the most to up to date information available to safely navigate foreign waters and ports as new information of changes to sea depths, sand bars, wrecks or other any other pertinent nautical information that could hinder passage became available. As updated charts were offered for sale, the earlier outdated charts in the hands of mariners, pilots, ships owners and sailors were invariably discarded, subsequently making all British Admiralty issued hydrographic charts of the period rare.
