Washington 29 February 1828.
The enclosed small packet, addressed to your lady, has just been received from Mr Hughes, our Chargé d’Affaires to the Netherlands. To account for its present appearance, I have to remark that it was by Mr Hughes transmitted to me open, with permission, of which I have availed myself to peruse its contents. To this indulgence of Mr Hughes I am indebted not only for the knowledge of the interesting incident related by him, but for the opportunity which it affords me of requesting you to make acceptable to Mrs. Madison, the assurance of my highest respect, as well as of renewing to yourself that of my constant and grateful attachment—
