On his discovery of ova of Flustra.
"Pray do not call me Dr Darwin."
Thanks for information [about early evolutionary views of Alexander Braun].
Sends specimens of Russian wheat variety kubanka, which after sowing for two years degenerates into a different variety, saxonka. Suggests that ASW conduct experiments.
Thanks for specimen.
Always was sceptical of James Buckman’s experiment; heard afterwards that cruel trick was played on him.
Glad ASW is willing to look into Russian wheat case.
CD believes few or none have attributed deaf-mutism to consanguineous marriages.
Julius von Sachs will "swear & curse" when he finds out he has missed sensitiveness of root apex. Has been putting his notes together and the case is conclusive. [Dated "Saturday 10th" by CD.]
Has had conflicting information on the movement of radicles; wants FD to experiment with them.
Criticises article by TM. "Such a manner of treating the work of other observers did not appear to me the way to encourage truth."
Thanks FL for the Plantago specimens. FL’s view of the stages by which the plant has become gynodioecious seems very probable.
Remits subscription as requested by EWF as the Knockholt & Chevening Footpath Fund [see 11535].
Discusses EM’s book [Die Dolomit-Riffe von Südtirol und Venetien (1878–9)]. Pleased by EM’s views of geological chronology based on evolution. Thinks distribution of land and sea formerly very different. New genera and families may have been developed on isolated tracks and migrated.
Comments on achenia of Pumilio argyrolepis.
Sends letter and seeds from [F. J. Cohn].
Is working too hard.
Feels WHK’s views on the origin of tumbling in pigeons are very likely correct.
Has been observing the movements of leaves and cotyledons; sleep movements are exaggerated circumnutation. Reports some odd observations on movement in Oxalis species.
Can send FD twisted branches of some climbing plants if he wishes.
Asks questions related to movement in plants. The cotyledons of Oxalis offer a promising field for study.
Wonders why Julius von Sachs thinks bloom is a protection against insects.
Encloses notes on the cotyledons of Oxalis species.
Congratulates JWJ on marriage.
Thanks for essay by Neumayr [see 11569].
Comments on paper by Edmund Mojsisovics ["Kleine Beiträge zur Kenntniss der Anneliden", Sitzungsber. K. Akad. Wiss. Wien Math.-naturwiss. Cl. 76 (1877) Abt. 1: 7–20].
CD’s health better than a few years ago.
Discusses methods of fertilising potatoes.
Will dispatch the best twisted stems he can find.
Considers the role of the pulvinus in leaf movement.
