Captain (Sir) John Ross commanded the Victory during his second Arctic exploration (1829—1833), partly in order to regain credibility after charting a fictional landform, Croker Mountains, during his first Arctic expedition.

[3] Upon returning to England in 1833, the expedition's members learned that the Duke of Clarence had ascended to the throne in 1830, becoming King William IV.

seemed much tickled at this subject - he was not one he said to take away a man's fair character, but there were some things that ought to be held up to reprobation, and he was now going to tell me a good story.

He had the book brought him and he asked me how many islands I counted in the Clarence group.
