The "London Quarterly Review" began with the observation that "When an intelligent man tells us that he has spent eleven of the best years of his life in any district, we may be pretty sure he has something to say about it which will interest even those who generally find travels dull reading". The reviewer finds Bates among the most readable, and free of the usual "personal twaddle" of travel and adventure books. The reviewer also remarks on Bates's subtitle "...of the origin of species", that Wallace had taken up that theme more fully. In the reviewer's opinion, Bates says little about "the Darwinian hypothesis", focusing instead steadily on natural history, while making "very shrewd remarks" about human society and giving "most glowing" descriptions of tropical scenery. The reviewer notes that most of the people Bates meets "had a tinge of colour" but made the "lonely Englishman" comfortable with their "winning cordiality", and is amused that in a feast in Ega an Indian dressed up as an entomologist, complete with insect-net, hunting-bag, pincushion, and an old pair of spectacles. As for nature, the reviewer considers that "in Brazil man is oppressed, crushed, by the immensity of nature".
