chunk: After their adventures in the South Sea Islands, Jack Martin, Ralph Rover, and Peterkin Gay go their separate ways. Six years later, Ralph (again the narrator), living on his father's inheritance on England's west coast and occupying himself as a naturalist, is visited by Peterkin, whose "weather-beaten though ruddy countenance" he does not recognize. Peterkin, who has stayed in touch with Jack, has hunted and killed every animal on Earth except for the gorilla and now comes to Ralph to entice him on a new adventure. After Peterkin writes him a letter, Jack joins the two, and they leave for Africa.
