I have recd. from Mr. H. Wheaton who is engaged in a Biography of the late W. Pinkney a letter wch. I inclose with my answer.1 If your recollection or memoranda can confirm or enlarge the information I have given with respect to the origin of the Embargo, be so good as to return my answer that it may be improved: If otherwise, it may be sealed & forwarded; the letter from Mr. Wheaton to be returned in either case. I infer from a former letter from Mr. W.2 that his work will probably embrace somewhat of a historical review of the Biographical period.
