_July 2, 1862_.
_To the Senate of the United States_:
I herewith return to your honorable body, in which it originated, an act
entitled "An act to provide for additional medical officers of the
volunteer service," without my approval.
My reason for so doing is that I have approved an act of the same title
passed by Congress after the passage of the one first mentioned for the
express purpose of correcting errors in and superseding the same, as I
am informed.
