Reactions of Candolle, Naudin, Decaisne, and Gaston de Saporta to Origin.

CD’s new hothouse.

CD’s Linum paper.

JDH’s work on Welwitschia.

Thanks FR for sketch of progress of evolutionary theory in Germany.

Compliments to Gustav Jäger.

Comments on FR’s book [Ch. Darwin’s Lehre (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.

Thanks RT for his letter and MS.

Is astonished by the different forms of orchids he describes.

Urges RT to describe and experiment with two or three of the more distinct genera.

"I believe, or am inclined to believe in one or very few primordial forms, from community of structure and early embryonic resemblances in each great class."

CD thinks that he believes in as much migration as AdeC, only he does not believe nearly so much in continental extensions. CD also believes more in modification in form though he suspects the difference is not so great.

Thanks AdeC for information on melons, oranges,

and Swiss lake-habitation discoveries.

CD is almost tired of his book on variation under domestication, for his knowledge is insufficient to treat the plant part well, but he has done so much that he will finish it.

Thanks for CD’s experimental suggestions. Will count seeds of hybrid crosses.

Requests suggestions for Edinburgh Botanical Society expedition to British Columbia.

Now recalls a Melastoma visited by some small Cetoniadae and bees (Xylocopa) in Malay Archipelago.

Has signed for the shares. Fears CD’s "good time" has not lasted long.

Will supply CD with information "as far as my knowledge extends".

Suggests CD visit him.
