Has given CD’s queries about expression to W. H. Stirling. Thomas Bridges, the catechist, had previously answered some questions incompletely [see 2643]; BJS forwards them [see Expression].

BJS answers CD’s query about when some calves show their adult colour.

Discusses a rare shell found by BJS on the Beagle voyage, an account of which has just been written by Davidson [possibly in Ann. & Mag. Nat. Hist. 3d ser. 20 (1867): 81–3].
