 In 1850, at the age of 72, Ross undertook a third voyage to the Arctic regions, this time in search of the expedition party of Sir John Franklin which had not been heard from for four years.With financial support from Lady Franklin, he sailed a private vessel, the schooner "Felix", to Lancaster Sound.His vessel was not particularly robust and other ships in the area had to provide food to help Ross combat scurvy which had set in amongst his crew.
