1871. Dec. 9

My dear Sir

〈    〉 your letter 〈    〉 April 5th (if it 〈    〉 ago as to〈    〉) gave me spirit 〈    〉 writing to you again, by asking me to observe whe〈ther〉 the platysma myoides contracts

(2) during a shivering fit.1

The nearest approach to extreme terror that I have felt since then, has been caused by the sight of a 〈pages damaged

But I am presuaded that all the facts are to be explained by reference 〈    〉 to the geometrical necessities 〈of m〉utual accommodation in the bud.3

Footnotes

CD had asked Airy to observe whether the platysma muscle contracted during extreme terror or a shivering fit (letter to Hubert Airy, 5 April [1871]).
The chancellor of the Exchequer was Robert Lowe.
For CD’s interest in phyllotaxy, see the letter to Chauncey Wright, 13 and 14 July [1871] and n. 7. Airy’s views on phyllotaxy were later published in a paper communicated by CD to the Linnean Society (Airy 1873); he argued that complex leaf arrangements had developed primarily to make the most economical use of space in the bud.
