CD thanks AN for the note and remarks on the partridge’s leg. CD is too ill to write a note, but will send [for] the specimen as soon as he can. [See 4326.]

Returns a borrowed extract from the [Zoological?] Record.

Asks whether he ought to write to CD while he is ill.

Wonders if he might use Haast’s notes on introduced animals for a notice he is preparing ["Note on the replacement of species in the colonies and elsewhere", Nat. Hist. Rev. n.s. 4 (1864): 123–7].

CD agrees about reversion.

The discovery of crossing in cryptogams is very interesting.

CD’s Copley Medal. The numbers were ten to eight in CD’s favour but the Cambridge men mustered strongly for Sedgwick.
