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.
