Of the whole crew (and the total ship's company numbered 83) only two caused any trouble to the commander. As these two "required more severity in reducing to good order than I wished to exercise in a service of this nature," when the Investigator reached the Cape, Flinders arranged with the Admiral there, Sir Roger Curtis, to exchange them—as well as two others who from lack of sufficient strength were not suitable—for four sailors upon the flagship, who made a pressing application to go upon a voyage of discovery. Thus purged of a very few refractories and inefficients, the ship's company was a happy, loyal and healthy crew, of whom the commander was justifiably proud.
The officers and scientific staff were chosen with a view to making the voyage fruitful in utility. The first lieutenant, Robert Fowler, had served on the ship when she was the Xenophon. He was a Lincolnshire man, hailing from Horncastle, and had been a schoolfellow of Banks. But it was not through Sir Joseph's influence that he was selected. Flinders made his acquaintance while the refitting of the vessel was in progress, and found him desirous of making the voyage. As his former captain spoke well of him, his services were accepted. Samuel Ward Flinders went as second lieutenant, and there were six midshipmen, of whom John Franklin was one.
Originally it was intended that Mungo Park, the celebrated African traveller, who was at this time in England looking round for employment, should go to Australia on the Investigator, and act as naturalist. But no definite engagement was entered into; the post remained vacant, and a Portuguese exile living in London, Correa de Sena, introduced to Banks a young Scottish botanist who desired to go, describing him as one "fitted to pursue an object with a staunch and a cold mind." Robert Brown was then not quite twenty-seven years of
