Dear Mr Darwin
I beg of you to accept my very sincere thanks for your kindness in granting me permission to make use of the illustrations in your admirable work on the Orchids,1 which I have taken the liberty to refer to very extensively in a sketch on the present state of microscopic science which I have just finished2
Believe me | very gratefully yours | Mary Somerville
