Summary
Sends CD a paper ["Ant-agency in plant structure", published in Spruce Notes of a botanist on the Amazon and Andes, ed. A. R. Wallace (1908)] on plant structures he believes are the work of insects; asks him to forward it to the Linnean Society [read 15 Apr 1869].
Writes of his support for the Origin, before which he had been much concerned by the delimitation of so-called species.

To Richard Spruce 1 April 1869
Summary
RS’s facts are remarkable. A year or two ago CD would not have believed ants could produce an inherited effect, but he has "lately come to believe rather more in inherited mutations". However, CD is not satisfied that the sacs are inherited and urges RS to produce any other evidence he might have.
