From Hubert Airy 17 March 1873
Summary
Thanks for congratulations on appearance of abstract of HA’s paper [Nature 7 (1873): 343–4].
Explains again his theory of "contraction with twist" by which compact buds and a spiral phyllotaxy have evolved. Explains how the peculiar phyllotaxy of the teasel is explicable by this process of "condensation".
