To W. T. Thiselton-Dyer 23 November [1880]
Summary
WTT-D’s suggestion about absorbent function of pegs in Abronia suggests origin of pegs in Welwitschia, which deeply interests CD. Previously could not see how pegs became large enough to be of mechanical use. Now thinks tissue between hypocotyl and radicle absorbs fluid, which would favour rise of peg to expose larger surface.
Rejects German contempt for investigating use of organs.
Asks WTT-D to observe how worms draw Robinia leaves into burrows.

Summary
CD may not mean same thing as WTT-D by absorbent pegs in Abronia.

Has observed earthworms for CD: they do not draw Robinia leaves into burrows by the petioles.
