This collection consists of notes on and drafts of Julian Huxley’s “Morphism and Evolution” as well as research materials and correspondence related to his work.

The Max Nicholson/Julian Huxley papers consist of correspondence, documents, typescripts, articles, and off-prints (c. 1927-1980s) relating to Nicholson's collaboration with his contemporaries (including Julian Huxley) on projects such as the Idea Systems Group and publication of The Humanist Frame.
