To J. S. Burdon Sanderson 16 July 1875
Summary
Thanks for JSBS’s essays; wishes he had said something on Lister’s observations. Speculates on the fungoid nature of smallpox and why there is seldom re-infection.
Discusses digestion by Drosera, the action of its secretion being the same as that of gastric juice.

To J. S. Burdon Sanderson 29 March 1873
Summary
Reports that he has not received JSBS’s book on histology and physiology [Sanderson ed., Handbook for the physiological laboratory (1873)], which Edward Emmanuel Klein told CD’s son was to be sent. He asks for information so that he may thank Dr Klein. [Klein and Michael Foster were co-authors with JSBS.]
He has returned the Gazette to Dr T. L. Brunton. [See 8825.]

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.

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.

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.
