A complete transcript of Darwin's Beagle Journal.
Darwin's Beagle diary is a Boys' Own adventure story: storms, sea-sickness, floggings, jungle adventures, volcanoes, earthquakes, tsunamis, savages, in-land treks, river journeys, gauchos, battles, the return of alien abductess—they're all in there.
Wonderful.
