From Hubert Airy   9 December 1871

Flamsted House | Greenwich S.E.

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

(1) during extreme terror, or

(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⟩⁠

be present) I heard the Chancellor of the Exchequer deliver a capital speech, the greater part of which ⁠⟨⁠I⁠⟩⁠ should describe, to any one but yourself, as a Darwinian manifesto—2 There were no reporters in the room, and I cannot be ⁠⟨⁠sure⁠⟩⁠ of his exact words, but he ⁠⟨⁠several words missing⁠⟩⁠ to the hopefulness ⁠⟨⁠2 or 3 words missing⁠⟩⁠ he looked forward to ⁠⟨⁠the⁠⟩⁠ time when the general ⁠⟨⁠    ⁠⟩⁠ recognition of the truth ⁠⟨⁠    ⁠⟩⁠ great doctrine of evolution ⁠⟨⁠    ⁠⟩⁠ lead to the general de⁠⟨⁠velop⁠⟩⁠ment of a spirit of uni⁠⟨⁠versal⁠⟩⁠ charity towards all things ⁠⟨⁠    ⁠⟩⁠ on the earth. ⁠⟨⁠On⁠⟩⁠ the other hand, at a ⁠⟨⁠meet⁠⟩⁠ing of a Literary Society at a ⁠⟨⁠    ⁠⟩⁠ town in the north, one ⁠⟨⁠  ⁠⟩⁠nth, I heard a paper ⁠⟨⁠pages damaged⁠⟩⁠

but I take advantage of the occasion to ask if you know of any paper or treatise dealing with the facts of leaf arrangement by your theory— ⁠⟨⁠    ⁠⟩⁠ scrutable marvels of ⁠⟨⁠    ⁠⟩⁠ (!) are the pleasure-grounds ⁠⟨⁠    ⁠⟩⁠ ⁠⟨⁠evo⁠⟩⁠lutionists, and they revel ⁠⟨⁠to their hear⁠⟩⁠ts’ content in their ⁠⟨⁠  ⁠⟩⁠ries of arithmetic ⁠⟨⁠several words missing⁠⟩⁠ they carry far ⁠⟨⁠    ⁠⟩⁠ limits found in nature, ⁠⟨⁠    ⁠⟩⁠ mystery of ⁠⟨⁠    ⁠⟩⁠ angle, between one-half ⁠⟨⁠and⁠⟩⁠ one-third of 360o, which has no representative at all in nature. 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

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.
