Sends some trees to CD.

Would be pleased to receive the copy of Origin offered by CD as gift.

Will give CD any tree or shrub he may want.

Refers to curious strawberry hybrids noticed in Journal of Horticulture [I. Anderson-Henry, "Crossing strawberries", J. Hortic. n.s. 4 (1863): 45–6].

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.

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.

His observations of "selection" in growth of seedling trees.
