To G. G. Stokes   11 March [1868]1

4 Chester Place | Regents Park | N.W.

March 11th

My dear Sir

After writing to you I suddenly remembered that there were albino Peacocks, of which I enclose the two best, but very poor, feathers which I could get.2 On one of these I can see no eye; on the other, when held obliquely, a trace of the eye. These feathers, I suppose, show how true your view is that the colours are due to a thin coloured film.—3 I thought that you possibly would like to see these feathers & that it wd. give you no trouble to receive them & throw them away.

If you can at any time tell me whether the successive zones of colour require films of different colours, or may be caused by a change of thickness or some other change in a uniformly coloured film, I shd be grateful. During next 3 weeks my address will as above;4 afterwards at my home, “Down Bromley Kent”.—

Pray excuse me troubling you & believe me | Yours very truly obliged | Ch. Darwin
