Darwin's Beagle Notebooks, Down House, Downe, Greater London
Detailed view of Charles Darwin's Beagle notebooks. Darwin was aboard the Beagle during her five-year survey voyage to South America and the Pacific. During this time he made observations which would underpin his theory of evolution. Darwin later wrote: "Let the collector's motto be 'Trust nothing to memory', for the memory becomes a fickle guardian when one interesting object is succeeded by another still more interesting." The notebooks are now in the care of English Heritage (2011).
