Geographical features including Rat Island, off the coast of Uruguay, and St Michael's Mount in the islands of Fernando de Noronha, off the north-east coast of Brazil. One of 14 scenes by Lieutenant E N Kendall portraying the coasts and islands of the South Atlantic, made during the voyage of HMS 'Chanticleer' under Captain Henry Foster. The purpose of the voyage was to ascertain the formation and outline of coasts and the direction of the principal ocean currents in both hemispheres. Foster took gravity observations and measurements, particularly by means of a Kater invariable pendulum. His research was published in 'Relation of a Journey through the South Atlantic, made upon the Royal Corvette 'Chanticleer' during the Years 1828-1831' (London, 1834).
