Seventieth birthday greetings.
HM’s teaching methods and his ideas are under attack in Germany along with the works of Ernst Krause.
HM intends studying bees to find evidence supporting CD’s theories. His work has shown him there are problems in separating species from varieties, and has also revealed many surprising instances of variation in habits.
Is preparing a work on fertilisation of flowers, and wants to add a list of works containing observations on cross-fertilisation of plants. Asks CD for any references he may have.
Thanks CD for MS on the routes of male bees.
His "Fertilisation of flowers" is complete [Die Befruchtung der Blumen (1873)].
Sends his book [Die Befruchtung der Blumen (1873)]. Hopes CD will publish an opinion of it.
Praises Expression.
Reports on Fritz Müller’s observations of cross- and self-fertilisation. HM will cultivate the two forms [i.e., mainly self-fertilised and mainly cross-fertilised] in the way CD has described.
He continues his observation of wild flowers. Encloses drawing of Viola tricolor with notes on its self-fertility.
Thanks for CD’s praise of his book [see 8901].
Poa annua shows putative evidence of nectar secretion in grasses. He will continue observations as CD requests.
Reports on insects fertilising Viola tricolor and on the fertilisation of the two wild forms [see Cross and self-fertilisation, p. 124 n., 125].
Sends a note on R. Caspary’s observations of Corydalis self-fertilisation [see Cross and self-fertilisation, p. 331].
Has begun his experiments on the self- and cross-fertilised flowers.
Fritz Müller is now working on the Brazilian honey-bees (Melipona and Trigona).
HM thanks CD for fertilisation references.
Feels CD’s and Fritz Müller’s judgments on his "Anwendung" essay [see 8313] are of highest value. Mentions some of FM’s comments.
Looks forward to second English edition of Descent.
