From Hubert Airy 24 July 1872
Summary
Responds to CD’s comments on his MS on phyllotaxy.
The initial variation required by his theory would be a slight twist of the bud-axis; believes the frequent twisting of stems and branches renders such a variation possible.
Admits he placed too much emphasis on the importance of frost. He should have spoken more generally of "vicissitudes of climate".
