[Julian Huxley, biologist, first director of UNESCO, as Secretary of Zoological Society of London.] Typed Note with cyclostyled signature, informing Dr Maurice Ernest that he does not consider the 'main thesis' of his book 'biologically justified'.

1p, 4to. In good condition, lightly aged. Folded three times. Cyclostyled signature: 'Julian S. Huxley'. Addressed to 'Dr. Maurice Ernest, | New Court, | Esher, | Surrey.' He apologises for having been unable to read his book, adding: 'I am afraid I cannot feel that your main thesis is biologically justified'. It is obvious why Huxley did not look beyond the title, as the book he is clearly referring to is Ernest's 'Lives of 300 years and continual rejuvenation' (1942). A collection of the papers of the Austrian-born biologist Maurice Ernest (1872-1955) is in the University of Chicago Library. In addition to longevity, Ernest's interests included homeopathy: his 'Everyday Chronic Maladies' went through numerous editions.
