Sends letter and seeds from [F. J. Cohn].
Is working too hard.
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.
Feels WHK’s views on the origin of tumbling in pigeons are very likely correct.
Pleased with CD’s praise of his work. He agrees with CD that intermediate marine fossils are rare in the same bed. The difficulty is overcome by extensive search of "isotopic" fauna in different beds of the same "isotopic" region.
Suggests sensitive plants that close at night would be protected from nocturnal-feeding snails. JIR’s brother in India says snails occur there in abundance.
Sends article on "Evolution" [Encyclopaedia Britannica, 9th ed.]. CD will be interested in Lamarck’s opinions in 1794.
Is working on crayfish and their distribution.
JDH’s scheme for lowering F.R.S. fees by creating a fund through membership subscription.
Report of an "eight legged horse" considered to be an example of reversion.

Would like to read Weismann’s essay on Daphnidae.
Fritz Müller’s paper on odours emitted by butterflies was read at last Entomological Society meeting.
Comments on positive response to publication [of Atlas]. CD’s approval will help make an English edition possible. Rejects suggestion that CD should subscribe.
Has been observing the movements of leaves and cotyledons; sleep movements are exaggerated circumnutation. Reports some odd observations on movement in Oxalis species.
Seeks CD’s support for W. C. M’Intosh, candidate for Chair in Natural History at Aberdeen.
Can send FD twisted branches of some climbing plants if he wishes.
Sends CD a copy of his book [Flowers; their origin, shapes, perfumes and colours (1878)].

No summary available.
Sends a paper by Melchior Neumayr [‘Über unvermittelt auftretende Cephalopodentypen’, Jahrb. K.-K. Geol. Reichsanst. 28 (1878): 37–80].
Plans to marry soon.
Next year he will begin a practical course in geology to supplement his lectures.
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.
