Lieutenant Fitzmaurice was at Valparaiso in 1803, and he states that all British prisoners in Chili and Peru had been released, and that he had heard of Mr. Bass being in Lima five or six years before. A letter in the Record Office, London, dated Liverpool, New South Wales, December 15th, 1817, says:-- "I have just heard a report that Mr. Bass is alive yet in South America. A capt'n of a vessel belonging to this port, trading among the islands to the east, fell in with a whaler, and the capt'n informed him he had seen such a person, and described the person of Mr. Bass. The capt'n, knowing Mr. Bass well, is of a belief that, [from] the description that the master of the whaler gives of him, it's certainly Mr. Bass, being a doctor, too, which is still a stronger reason. I am, etc., THOS. MOORE." And so in this sad fashion, his fate a mystery, perhaps the victim of savages on some lonely Pacific island, perhaps dragging his life out a broken-hearted prisoner in the mines of Peru, the gallant young explorer passes out of history. When Flinders returned to England he found an enthusiastic admirer and a powerful friend in Sir Joseph Banks. The young lieutenant was getting ready for publication a small book describing the circumnavigation of Van Diemen's Land, and while he was doing this Banks induced the Admiralty to prepare H.M.S. _Investigator_ for surveying service in Australian waters and give Flinders charge of her, with the rank of commander. Banks had everything to do with the arrangements for the expedition; and how much was thought of his capacity for this work is shown by a memo from the Secretary to the Admiralty in reply to a request [Sidenote: 1800] from the naturalist:-- "Any proposal you may make will be approved; the whole is left entirely to your decision." The _Investigator_, formerly the _Xenophon_, was a sloop of war, and was fitted out in a most elaborate fashion for the cruise, carrying with her an artist (Westall), a botanist (Brown), an astronomer (Crossley), and several other scientists. Among her officers were Samuel Flinders, second lieutenant and brother of Matthew, and a midshipman named John Franklin, afterwards Sir John Franklin, the Arctic explorer and at one time governor of Tasmania. Her total complement numbered 83 hands. The _Lady Nelson_, a colonial government brig, was ordered, on the arrival of the _Investigator_ at Port Jackson, to join the expedition and act as tender to the larger vessel, and her history is scarcely less remarkable than that of the little vessel _Norfolk_, Flinders' old command, which by this time had been run away with by convicts, and "piled up" on a beach near Newcastle, New South Wales.
