Many thanks for Expression. AG relates some relevant observations, the significance of which had previously escaped him.

Thanks AG for Popular Science Review containing his article [on Ceratodus, 11 (1872): 257–66]. CD had already read it with great interest.

CD did not bring any tortoises back from the Galapagos. There may be specimens at the Military Institution in Whitehall.

Sorry AG was unable to lunch with the Darwins during their stay in London.

Apologises for having given CD some unreliable information.

Thanks AG for information [unspecified]; so trifling an error will not alter his opinion that AG is "the most accurate of men".

Asks AG to sign an enclosure [see 9291].

Signs Robert Swinhoe’s certificate [for the Royal Society] with pleasure.

Has given in Descent 2: 12, an account from AG of the brushes on the sides of Monacanthus; has now learned of brush-like scales on the males of Mallotus. Asks whether the two genera are related.

Comments on several points in Descent,

doubts facts about Monacanthus brushes

and the two Cyprinidae males attending the female when spawning.

Encloses a circular [9384?] to explain the predicament he is in. Asks whether AG can get anyone at the British Museum, other than Owen, to join J. E. Gray in signing.

Believes the account of the Mallotus in American Naturalist [5 (1871): 119] is trustworthy.

Invites AG to stay at Down.

Thanks for recent edition of CD’s Journal of researches.

Has been appointed to a Keepership at British Museum.

Rejoices at AG’s "honourable & important" position [Keeper of the Zoological Department, British Museum].

Has signed certificates.

His specimen catalogue has not been returned from Cambridge museum. If not lost, will answer query.

Discusses spider specimens.

Pigeons’ skins dispatched today.

Sends MS about pigeons.
