This chart depicts the routes of the British ships HMS Carcass and HMS Jason during their survey of the Falkland Islands in 1766. The two northwestern-most islands were named after the two vessels. A few English and French settlements are shown, and the islands are surrounded by depth soundings, anchorages, rocks, and shoals. Above and at bottom right are 9 coastal approach views of the Jason Islands, formerly called the Sebaldine Islands by the Spanish. The map is based on a chart by Captain Macbride, who commandeered the HMS Jason and published an account of the survey in A Journal of the Winds and Weather ... at Falkland Islands in 1767.
