Asks about movement of Euphorbia.
Is doubtful about the publication of Fritz Müller’s letter after so long an interval.
Young Belgian students [L. A. Errera and Gustave Gevaert] ask CD to read their paper, which summarises Cross and self-fertilisation. They criticise CD’s views on the comparative effects of crossing flowers on the same stem and fertilisation of a flower by its own pollen ["Sur la structure et les modes de fécondation des fleurs", Bull. Soc. Bot. Belg. 17 (1878): 38–181, 182–248].
Wants a Euphorbia to test for leaf movements.
Thanks JVC for correcting a bad blunder in Forms of flowers.
His health fairly good; has been able to work "pretty hard".
Agrees to look over MS.
Describes data relating to variability of Primula elatior.
Count Schouvaloff asserts that CD’s works are prohibited in Russia. Is he not mistaken?
No summary available.
Encloses Fritz Müller’s letter.
Is exhibiting butterflies in which variations in the female show a finely graded series. Believes dimorphism can be explained by the selection of the extremes of such a series and the consequent extinction of the intermediates.
Thinks the facts in Fritz Müller’s letter could be published.
Recommends August Weismann’s essay on dimorphism ["Über den Saison-Dimorphismus der Schmetterlinge", Studien zur Descendenz-Theorie 1 (1875)]
and has no doubt that intermediate forms could be eliminated as RM suggests.
Thanks for Euphorbia.
Asks for plants for "bloom" experiments.
Sends "worm journal" – observations of earthworm activity at Abinger.
Thanks THF for the diary of worm activity at Abinger site.
Has received CD’s book [Forms of flowers]; thanks him for the compliment of the dedication.
Does not think Fritz Müller can object to anything RM has said in his essay.
Has alluded to colour preference among butterflies in Descent [1: 400–1].
Thanks for Die niederen Pilze (Nägeli 1877).
Thanks for Australian leaves for "bloom" experiments.
Has noticed citation of his observations in CD’s latest books; writes to add some notes on fertilisation and forms of flowers.
Rejoices that SS has accepted his son [William]. Judging from his own experience "life would be a most dreary blank without a dear wife to love with all one’s soul".
