Sir Charles Lyell was President of the Geological Society at the age of thirty-eight in 1835, and a very good friend of Charles Darwin who wrote in his letter "The science of geology is enormously indebted to Lyell - more so, as I believe, than to any other man who ever lived". Sir Charles arranged for the publication of the views of Darwin and Wallace upon the origin of species and Darwin spoke of his house as his "morning house of call". It is a family tradition that these two casts were taken by Darwin on his famous voyage in the Beagle, but although Darwin may have given them to Lyell, it is unlikely that they were taken by him because he only had three short encounters with Aborigines and is likely to have recorded in his journal taking casts of their countenances had he done so.
