To Fritz Müller 7 February 1
Down. | Bromley. | Kent. S.E.
My dear Sir
I feel very guilty at not having sooner thanked you for your letter of Dec 1. which contained much valuable information.2 The reason has been that I have been very busy in making alterations in my M.S. for my book on domestic animals &c which is at last in the printer’s hands.3 I am very much obliged for the seeds of Cordia &c which are planted & if I can make them flower will be highly interesting to me.4 Your letter told me much on many points of value to me. You have communicated to me many more cases than any two or three botanists put together.
I have quoted your evidence on the self-sterility of Ocidium flexuosum;5 it is said to be a native of Brazil, but I much wish to know whether it is a native of your district.
I have many striking cases of similar self-sterility with Orchids, but have hitherto always attributed them to cultivation under unnatural conditions & this makes your case very interesting to me.6 This is a very dull letter, but I did not wish to defer any longer thanking you.
Believe me my dear Sir | yours very sincerely | Ch. Darwin
P.S. Would you be so good as to tell me whether I ought to direct to you as Professor or Dr Fritz Müller
CD’s Variation is in printer’s hands.
