On 24 August Henslow wrote to Darwin: ...that I consider you to be the best qualified person I know of who is likely to undertake such a situation— I state this not on the supposition of yr. being a finished Naturalist, but as amply qualified for collecting, observing, & noting any thing worthy to be noted in Natural History.
O 24 de agosto Henslow escribiu a Darwin dicindo: ...que eu considéroo a vostede a persoa mellor cualificada que coñezo que sexa probable que emprenda este traballo— Afirmo isto non supoñendo que vostede sexa un naturalista xa completo, pero si amplamente cualificado para coleccionar, observar e decatarse de calquera cousa que pague a pena tomar nota en Histoia Natural.
