TABLE IV.

OUTER, OR SEA COAST, OF TIERRA DEL FUEGO.

In order to adapt the longitudes of the places mentioned in this Table to the meridians of Port Famine and St. Martin Cove, at Cape Horn, the following corrections[209] have been made to Captain Fitz-Roy's chronometrical results, _viz_:--

Townshend Harbour } { 0'11"} Stewart Harbour } { 0 23 } to the Eastward of Captain Doris Cove } have been placed { 0 33 } Fitz-Roy's chronometrical March Harbour } { 1 6 } deductions.

Good Success Bay } { 2 0 }

By Captain Fitz-Roy's observations St. Martin Cove would be in long. 67 31' 18", which is 2' 15" to the Westward of the mean of upwards of thirty chronometrical results from Monte Video. The difference has, therefore, been equally divided between North Cove and St. Martin Cove; the longitude of the latter being taken at 67 29' 03", and of Port Famine at 70 54'.
