Sir: This department has learned with much sensibility of the kindness and courtesy shown by the authorities of Brazil to that distinguished man of science, Professor Louis Agassiz, during his recent visit for professional purposes to your interesting empire. The course of those authorities on the occasion referred to is regarded as showing an appreciation of the importance of Professor Agassiz’s researches which does them honor, and a regard for him personally as a citizen of the United States, requiring this special acknowledgment, which I have been directed by the President to make.

I avail myself of this occasion to render to you the assurances of my most distinguished consideration.
