chunk: Lord Glenarvan makes it his quest to find Grant; together with his wife, Grant's children and the crew of his yacht, the Duncan, they set off for South America. An unexpected passenger in the form of French geographer Jacques Paganel (he missed his steamer to India by accidentally boarding on the Duncan) joins the search. They explore Patagonia, Tristan da Cunha Island, Amsterdam Island, and Australia (a pretext to describe the flora, fauna, and geography of numerous places to the targeted audience).
