To J. S. Burdon Sanderson   26 June [1873]

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.
