Dear Mr. Darwin,
I send you today a copy of my Memoir on the Odontornithes, the plates of which I had the pleasure of showing you two years ago.1 I trust you may find in the volumes some new facts in confirmation of your own work, which has changed the whole course of scientific investigation.
I remain | with high respect, | very truly yours, | O. C. Marsh.
Charles Darwin Esq F.R.S. &c.
