To Fritz Müller 9 December 1
Down. | Bromley. | Kent. S.E.
My dear Sir
I have received your interesting letter of Oct. 10th. with its new facts on branch-tendrils.2 If the Linn. Soc. publishes your paper, as I am sure it ought to do, I will append a note with some of these new facts.3
I forwarded immediately your M.S. to Prof. Max Schultze but I did not read it, for German hand writing utterly puzzles me, & I am so weak I am capable of no exertion: I took the liberty however of asking him to send me a copy if separate ones are printed;4 & I reminded him about the spunge paper.5
I knew of the difference in the spicula, but your difficulty had not occurred to me; from analogy I should rather expect that spunges have existed with spicula of the 2 kinds, & that the one had ultimately preponderated over the other.6
You will have received before this my book on Orchids & I wish I had known that you wd have preferred the English edition. Should the German ed. fail to reach you I will send an English one.7
That is a curious observation of your daughter about the movement of the apex of the stem of Linum & wd I think be worth following out; I suspect many plants move a little, following the sun; but all do not for I have watched some pretty carefully.8
I can give you no Zoological news for I live the life of the most secluded hermit.
I occasionally hear from Ernst Haeckel who seems as determined as you are to work out the subject of the change of species. You will have seen his curious paper on certain Medusæ reproducing themselves by seminal generation at two periods of growth.9
With sincere respect | Believe me my dear Sir | Yours very truly | Ch. Darwin
Has forwarded FM’s MS to Max Schultze, but did not read it.
