It is interesting that this map is entitled "Patagonia", treating it as a discrete geographical entity. Nevertheless, its political status was less settled. A note at the head of the map reads: "That portion of Patagonia east of the Andes is claimed by the Argentine Republic, and all west including the Islands, is occupied by Chili." Surprisingly, degrees of longitude are expressed relative to Washington.

Caution: There are some inaccuracies, especially in the depiction of the Pacific coastline.
