Lord Hertford's appointment to the French Embassy, and invitation to Hume to accompany him--Correspondence on the occasion--Residence in London, and remarks on the Political Movements of 1763--State of his reputation in France--His Arrival--Letters to friends at home about his flattering reception--The young French princes--Observations on eminent French people--His recommendations to a Clergyman-- Introductions of Fellow Countrymen. On the conclusion of the treaty of 1763, the Marquis of Hertford was appointed ambassador to the court of France. He invited Hume to attend him as secretary; and there is no reason to believe that the selection was owing to any other motive than the desire to place an able and honest man in office. The Marquis was a man of high moral character, and his religious opinions appear to have been considered by some of his contemporaries as too zealous and exclusive. The intercourse thus occasioned, was the commencement of a lasting friendship, in which the English Marquis and the Scottish philosopher, however separated by nominal difference of rank, had too genuine a respect for each other to be affected by such inequalities. The intimacy extended to General Seymour Conway, the brother of the Marquis; and Hume's intercourse with them both, tends to confirm the impression which the portraits of the two brothers convey to the present generation, of dispositions open, kind, and artless. In reference to this event, Hume says, in his "own life," "I retired to my native country of Scotland, determined never more to set my foot out of it; and retaining the satisfaction of never having preferred a request to one great man, or even making advances of friendship to any of them. As I was now turned of fifty, I thought of passing all the rest of my life in this philosophical manner, when I received, in 1763, an invitation from the Earl of Hertford, with whom I was not in the least acquainted, to attend him on his embassy to Paris, with a near prospect of being appointed secretary to the embassy, and, in the meanwhile, of performing the functions of that office. This offer, however inviting, I at first declined, both because I was reluctant to begin connexions with the great, and because I was afraid that the civilities and gay company of Paris, would prove disagreeable to a person of my age and humour: but on his lordship's repeating the invitation, I accepted of it. I have every reason, both of pleasure and interest, to think myself happy in my connexions with that nobleman, as well as afterwards with his brother, General Conway." We have, in his familiar correspondence, a fuller account of his feelings on the occasion. HUME _to_ ADAM SMITH. "_Edinburgh, 9th August, 1763._
