On HM’s Befruchtung der Blumen [1873].
Comments on Fritz Müller’s article on Hedychium.
Thanks HM for his review [of Forms of flowers, Kosmos 2 (1877–8): 286].
Thinks HM’s previous article was very important [Kosmos 2 (1877–8): 128–40]. CD will "heartily rejoice" if HM has explained the steps by which Rhamnus and Valeriana have been rendered dioecious.
Writing on vegetable physiology.
Nothing in CD’s life has ever interested him more than the fertilisation of such plants as Primula and Lythrum.
Has just heard that HM has been treated shamefully by his Government. What has happened?
Enjoyed HM’s castigation of Gaston Bonnier ["Gaston Bonniers angebliche Widerlegung der modernen Blumentheorie", Kosmos 7 (1880): 219–36].
Has heard of flood from which Fritz Müller escaped. Has he lost books, microscope, apparatus? Offers £50 or £100.
Has learned that Fritz Müller is HM’s brother.
Made aware by Asa Gray of error with respect to Cypripedium. Does not doubt it is self-fertilised.
Offers to undertake publication of English translation of Fritz Müller’s Für Darwin. W. S. Dallas will translate it.
Pleased HM says good words for Pangenesis.
Interested that HM is studying structure of insects in relation to flowers.
Comments on HM’s book [Die Befruchtung der Blumen (1873)]. Particularly glad to read historical sketch and discussion of work of C. K. Sprengel.
