To Daniel Oliver 15 November 1871
Down, | Beckenham, Kent.
Nov 15 1871
Dear Professor Oliver
Will you have the kindness to give me a small piece of information. Is it now believed that the spungeoles at the extremity of the rootlets secrete carbonic acid or any other element in a nascent state, which acts on bones & rocks so as to obtain the necessary phosphates & alkalis?1
I remember years ago having seen a statement to this effect, & I am anxious to know whether it is now thought true.2
Pray excuse my troubling you & believe me | yours sincerely | Ch. Darwin
