Excerpt on his trip to Brazil:
“During the remainder of my stay at Rio, I resided in a cottage at Botofogo Bay. It was impossible to wish for any thing more delightful than thus to spend some weeks in so magnificent a country. In England any person fond of natural history enjoys in his walks a great advantage, by always having something to attract his attention; but in these fertile climates, teeming with life, the attractions are so numerous, that he is scarcely able to walk at all.”
And of course, now we also have The Darwin project.
