Thanks JvH for his address [to the Philosophical Institute of Canterbury], his Geological Report [Topographical and geological exploration of the western districts of the Nelson province, New Zealand (1861)],

and for the "honourable" notice of Origin.

CD especially interested in JvH’s facts on the old glacial period.

Asks about fossil remains [of supposed living mammalia] which CD thinks may be like "the Solenhofen bird-creature" [Archaeopteryx].

Urges the recording of rate and manner of spreading of European weeds and plants and observation on which native plants "most fail".

Asks that a copy of Origin be sent to Thomas Rivers.

Curious about sale of Orchids. It is too stiff for the public. "If praise from Botanists would sell, it would go off well."

The number of "aquatic" flowers is reduced if one considers only those that expand under water.

Lecturing at Norwich.

Thanks WW for and comments on WW's Lectures on Political Economy. Has learned that the theory of rent is exploded. JH's daughter Julia is seriously ill.
