To Henry Denny 23 March [1865]
Summary
Interested by HD’s information on aperea; CD had concluded that it was not the progenitor of domestic guinea-pigs.
Is unsure what HD means by "stock-dove"; properly this is Columba oenas and the domestic pigeon is C. livia.
Suggests that the Zoological Society might arrange for some specimens [unspecified] to be supplied from the Gardens.
