To the Senate of the United States:
I nominate Andrew J. Donelson, of Tennessee, to be envoy extraordinary and minister plenipotentiary of the United States to the Federal Government of Germany.
In submitting this nomination I transmit, for the information of the Senate, an official dispatch received from the consul of the United States at Darmstadt, dated July 10, 1848. I deem it proper also to state that no such diplomatic agent as that referred to by the consul has been appointed by me. Mr. Deverre, the person alluded to, is unknown to me and has no authority to represent this Government in any capacity whatever.
