Would like Friedrich Anton Wilhelm Miquel’s photograph, but JDH should give CD’s address to FAWM.

Thanks for letter and glad Frances Harriet Hooker goes on well.

Do not send St Helena earth.

Hopes JM’s friend will give his judgment [on Variation] soon; and urges JM to come to a decision about publishing. CD believes it will have "a fair sale".

On final instalment of "Insular floras" [Gard. Chron. (1867): 75]; rejoices at extent of their agreement.

Some criticisms of JDH’s position on geographical affinities, and volcanic islands.

CD agrees to JM’s proposal of half-profits. Thinks it a mistake to print only 750 copies. The agreement on half-profit is for first edition only. CD estimates his book at a higher value than JM does.

Is convinced his chapter on man [for Variation] will excite plenty of attention and abuse, which he supposes is as good as praise for selling a book.
