Nicholas Lawson
Nicholas Oliver Lawson (born Nicolai Olaus Lossius, 23 November 1790 on Sekken, Norway;[citation needed] died 1 March 1851 in Valparaiso, Chile[citation needed]) was a Norwegian-born vice governor of Galápagos for the the Republic of the Equator (Ecuador). When the HMS Beagle survey expedition arrived at Charles Island (Floreana Island) in September 1835, Charles Darwin noted in his diary: "An Englishman Mr Lawson is now acting as Governor. — By chance he came down to visit a Whaling Vessel & in the morning accompanied us to the Settlement." Lawson described having seen a reduction in the numbers and size of Galápagos tortoises taken for meat by the whalers.[1] In his zoological notes, Darwin recorded that "It is said that slight variations in the form of the shell are constant according to the Island which they inhabit — also the average largest size appears equally to vary according to the locality.— Mr Lawson states he can on seeing a Tortoise pronounce with certainty from which island it has been brought." This was one of the points which led, later in the voyage, to Darwin's first doubts that species were immutable..[2][3]
