In naval and scientific circles Flinders was the object of much honour and interest. He was received "with flattering attention" at the Admiralty. We find him visiting Lord Spencer, who, having authorised the Investigator voyage, was naturally concerned to hear of its eventful history. Banks took him to the Royal Society and gave a dinner in his honour. The Duke of Clarence, afterwards William IV, himself a sailor, wished to meet him and inspect his charts, and he was taken to see the Prince by Bligh.
