Thanks for CD’s interest in his paper on plant movements ["Über die Ursachen der periodischer Bewegungen der Blumen und Laubblätter", Flora 56 (1873): 433–41, 449–55]. AFB concentrated on clear cases, though he knows there are others.

Experiments on function of movement: Mimosa leaves, held so they cannot move, die.

Comments on EM’s work in Dolomites [Die Dolomit-Riffe von Südtirol (1879)]. Had wondered whether ancient corals formed reefs.

Obliged for EM’s photograph. Sends his own.

No summary available.

Thanks CD for gift to support his research.
