My dear Sir
I am very much obliged to you for your great kindness in writing to me at such length about the colours of the peacock’s feathers.2 As you say that you will look at it again, will you have the kindness to attend to one point, namely, whether a gradual thickening or thinning by little steps from the centre to the circumference, of the film of colouring matter wd account for the zones of colour which occur; or must there be zones of different kinds of colouring matter?
With very sincere thanks | believe me my dear Sir | yours truly | Charles Darwin
Footnotes
Summary
Thanks GGS for information on the peacock’s feathers. Asks whether the colour zones around the "eye" could result from varying the thickness of the film of colouring matter or whether it would require different kinds of colouring matter.
