The first full edition of the notebooks used by Darwin during his epic voyage in the Beagle. It contains transcriptions of all fifteen notebooks, which now survive as some of the most precious documents in the history of science. The notebooks record the entire range of Darwin's interests and activities during the Beagle journey, with observations on geology, zoology, botany, ecology, barometer and thermometer readings, ethnography, anthropology, archaeology and linguistics, along with maps, drawings, financial records, shopping lists, reading notes, essays and personal diary entries.
