_To the Senate of the United States_:
I transmit herewith to the Senate a copy of a letter dated the 25th

Mr. Poinsett, envoy extraordinary and minister plenipotentiary of the
United States to Mexico, which letter contains, it is presumed, the
instructions a copy of which was requested by the resolution of the
Senate of the 28th ultimo in executive session.
