WASHINGTON, _January 28, 1862_.
_To the Senate of the United States_:
I submit to the Senate, for its consideration with a view to
ratification, a treaty of extradition concluded by Mr. Corwin with the
Mexican Government on the 11th of December last.
I also submit a postal convention concluded by that gentleman at the
same time, and a copy of his dispatch of the 24th of the same month
explanatory of the provisions of both these instruments, and the reasons
for the nonratification by Mexico of the postal convention concluded in
this city on the 31st of July last and approved by the Senate on the 6th
of August.
A copy of a letter from the Postmaster-General to the Secretary of State
in relation to Mr. Corwin's postal convention is also herewith
communicated. The advice of the Senate as to the expediency of accepting
that convention as a substitute for the one of the 31st of July last is
requested.
