The event now known as “the voyage of the Beagle” comprises Charles Darwin’s circumnavigation as ship’s naturalist on the second of three surveying voyages by H.M.S. Beagle; the writings published as his first book, the Journal of Researches; and the genesis of his theory of evolution by natural selection. Writing between regimes of world-knowledge, Darwin mediates scientific observation through the language of aesthetics, and seeks to understand the convergence of disparate scales of geological and human history.
