From O. C. Marsh   28 July 1880

Yale College | New Haven Ct.

July 28th. 1880.

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.

Marsh had visited CD on 9 July 1878 (Correspondence vol. 26, letter from W. E. Darwin, 10 July [1878]). CD’s copy of Odontornithes: a monograph on the extinct toothed birds of North America (Marsh 1880) has not been found.
