To Daniel Oliver   17 November 1871

Down, | Beckenham, Kent.

Nov 17. 1871

Dear Professor Oliver

You have been very kind to take so much trouble for me; the information is amply sufficient, as I wished to learn how far the roots cd act on rocks, not caring about the nutrition of the plants.1

Yours truly obliged | Ch Darwin

CD had asked Oliver whether it was believed that rootlets secreted carbonic acid or similar chemicals (letter to Daniel Oliver, 15 November 1871). Oliver’s reply has not been found.
