To J. S. Burdon Sanderson 1 October [1873]
Summary
Hears from Frank [Darwin] that Drosera behaves perversely. Suggests that motor influence may move longitudinally away from the excited glands.

Summary
CD can provide leaves of Dionaea if JSBS wishes to investigate electric currents in them.
His experiments show that the digestive action of Drosera seems like that of true digestion.

To J. S. Burdon Sanderson 9 September [1873]
Summary
Pleased JSBS has decided to work on Drosera; sends plants. Does not know whether thermo-electric pile could detect temperature change when leaves close.
CD’s experiment with very weak hydrochloric acid repeated with success: the plants digest albumen more quickly.

To J. S. Burdon Sanderson 26 June [1873]
Summary
Would welcome JSBS visit to discuss Drosera. Nitrogenous fluids can act as ferments only if they act merely by exciting molecular movement in adjoining molecules.
Glass and cotton excite movement and cause cell contents to change visibly. Huxley coming to see this phenomenon.
Studied effect of poisons 12 or 15 years ago to see whether the action was similar to that on nervous tissue.

From J. S. Burdon Sanderson 13 August [1873]
Summary
Answers CD’s questions of 25 July [8987] about temperatures at which cold-blooded animals are killed.
Doubts heat rigor was induced in Drosera. Gives his view of the relation of excitability to increase in temperature.
Suggests experiment to show that electrical changes in plant are the same as in animal muscle and nerve [see Insectivorous plants, p. 318].

To J. S. Burdon Sanderson 25 July 1873
Summary
Describes his recent work on Drosera digestion of organic materials, e.g., albumen and gelatin. Edward Frankland has given CD a rough test for pepsin. Some plant extracts cause as much inflection as meat. Has found some reversible inflection with heat and perhaps some heat rigor. Has measured the extreme sensitivity of Drosera with very dilute solution of ammonium phosphate.
