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.
