Down Bromley Kent
Dear & Honoured Sir
I write in haste to catch the Post just to say that I received this morning your ``Untersuchungen uber die Entwickelung'' & two copies of your ``Morphologische Studien'' (one of which I will give to some good man) & likewise your Portrait.
For all these most kind gifts I most heartily thank you.—
With sincere respect | Yours very truly obliged | Ch. Darwin
