To Thomas Rivers   7 January [1863]



Thanks for parcel of shoots with several interesting cases of "bud-variation".

Asks for information about roses.

Strange that great changes in peaches are less rare than slight ones and no case seems recorded of new apples or pears or apricots by "bud-variation". "How ignorant we are!"

To Thomas Rivers   17 [January 1863]


Can TR distinguish generally, always, or never, a nectarine-tree from a peach-tree before it flowers or before it fruits? He wants to quote TR’s answer.

From Thomas Rivers   26 January 1863


Thanks CD for Origin.

TR has often thought naturalists do not pay enough attention to the effect of site, soil, and climate on animals and plants and "hence has arisen the enormous number of so-called species".

His observations on people of different counties.

From Thomas Rivers   30 January 1863


Asks CD’s views on TR’s observations that leaves breathe from their under-surfaces.

Peach-trees in hothouses cannot be kept in health unless fresh air is admitted so as to make its way under the leaves.

Continues his observations on the effect of environment on men – those migrating to America gradually assuming Indian-like features.
