The Duke of Montagu was the Duke of Buccleugh's father-in-law, and the Rev. Mr. John Hallam--afterwards Dean of Windsor, and father of Henry Hallam, the historian--was the Duke's tutor at Eton, as Adam Smith was his tutor abroad. The freedom was therefore given to the Duke of Buccleugh and party. Smith's burgess-ticket is one of the few relics of him still extant; it is possessed by Professor Cunningham of Belfast. Smith promised Hume a visit about Christmas 1771, but the visit was postponed in consequence of the illness of Hume's sister, and on the 28th of January he received the following letter, in reply apparently to a request for the address of the Comtesse de Boufflers in Paris:-- EDINBURGH, _28th January 1772_. DEAR SMITH--I should certainly before this time have challenged the Performance of your Promise of being with me about Christmas had it not been for the misfortunes of my family. Last month my sister fell dangerously ill of a fever, and though the fever be now gone, she is still so weak and low, and recovers so slowly, that I was afraid it would be but a melancholy house to invite you to. However, I expect that time will reinstate her in her former health, in which case I shall look for your company. I shall not take any excuse from your own state of health, which I suppose only a subterfuge invented by indolence and love of solitude. Indeed, my dear Smith, if you continue to hearken to complaints of this nature, you will cut yourself out entirely from human society, to the great loss of both parties. The Lady's Direction is M^e la Comtesse de B., Douaniere au Temple. She has a daughter-in-law, which makes it requisite to distinguish her.--Yours sincerely, DAVID HUME. _P.S._--I have not yet read _Orlando Inamorato_. I am now in a course of reading the Italian historians, and am confirmed in my former opinion that that language has not produced one author who knew how to write elegant correct prose though it contains several excellent poets. You say nothing to me of your own work.[215]
