To J. D. Hooker 13 August 1873
Summary
Asks JDH why so many plants are protected by a thin layer of waxy matter or with fine hairs.
Wrote to John Smith for a plant of Oxalis sensitiva, but it has not acted well.
Rejoices over Ayrton’s retirement. Hopes W. P. Adam, his successor, is a good sort of man.

To J. D. Hooker 24 November 1873
Summary
Has been working hard on Mimosa albida. Could JDH ever make its opposite leaflets shut up close, as in sleep, when he irritated them? CD doubts they do, except in sleep. Thinks movement a protection against water.
Has examined only one specimen of Eucalyptus.
Cannot believe JDH’s results from cutting a hole in pitcher in his Nepenthes experiment.
