Your despatches to No. 74, inclusive, excepting Nos. 58, 54, 53, 52, 23, 16, have been received.

An extract of that part of your [despatch] No. 72, which suggests the propriety of your being allowed leave of absence, or to retire from the mission to Mexico, has been forwarded to the President, who is now in Tennessee.

This Department was not aware of the aversion of the Mexican Government to issue exequaturs upon the exhibition of copies of commissions. It is apprehended that you must be mistaken in saying that you had mentioned it. If communicated at all, the information must have been in some of your missing letters, duplicates of which you will forward without delay. The consuls, copies of whose commissions have been sent to you, will be directed to transmit to you the original documents; and the originals, instead of consular commissions, will, in future, be sent to you from the Department, for the purpose of procuring exequaturs.

In directing that the charges of Mr. Wilcocks should be made known to you, the President considered you as an official personage merely, against whom formal accusations and complaints were made by another officer of the Government. That the result of the investigation has justified the favorable judgment of your character he had formed on a personal knowledge, has been gratifying.
