To:
Charles Robert Darwin
Date:
14 Aug 1873
Source of text:
DAR 103: 167–8
Summary:

Has observed CD’s points. Except for leaves of Nelumbium, would have supposed both wax and hairs were connected with absorption or respiratory functions. May subserve some function connected with rays of sun. Watering most prejudicial in the hot sun: a splendid subject for experiments.

Adam is a good man.
