"One of the greatest of all classics of Australian exploration and discovery... Flinders' classic account of his voyage on board the Investigator records the full-scale expedition to discover and explore the entire coastline of Australia (which was the name that Flinders himself preferred and championed). The three volumes form a complete narrative of the expedition, including an authoritative introductory history of maritime exploration in Australian waters from the earliest times. The text contains a day-by-day account of the Investigator voyage and Flinders's later voyages on the Porpoise and the Cumberland. Robert Brown's "General Remarks, geographical and systematical, on the Botany of Terra Australis", which is illustrated by Ferdinand Bauer's botanical plates in the atlas, is printed as an appendix in the second volume. The text is illustrated by nine engraved plates and two double-page plates of coastal views in the atlas by the landscape painter William Westall, who travelled as official artist on the voyage. These are in many cases the very earliest views of the places visited and discovered on the voyage. Flinders' charts in the atlas were of such accuracy that they continued to be issued by the Admiralty for decades and form the basis of all modern charts of Australia. All the charts in the atlas here bear the imprint "W. & G. Nicol Pall Mall… 1814", an important point that identifies them all as being in the correct first issue form."
