Bartholomew James Sulivan took part in the second voyage of the Beagle, under Robert FitzRoy, and with Charles Darwin. From 1838 Sulivan conducted surveys in the Falkland Islands, his findings being incorporated into the South America Pilot. The portion relating to the Falkland Islands that appeared in the fifth edition of the Pilot (1860), was translated into French in 1869, and a translation into Spanish was made in the present work. A note at the front by the book’s former owner, Kenn Back, records that the first translation into Spanish of this portion of the South America Pilot was published in Madrid in 1865, but Back was unable to determine whether the present Chilean version is a new translation or a copy of the Madrid one.
