4. Count Ludovico Barbiano de Belgioioso (1728–1803) had recently turned from a military to a diplomatic career. He was Ambassador to St. James’s from the court of Vienna, 1769–83, and during his stay in London developed a wide circle of acquaintances, from the King to scientists and writers. He was subsequently the instrument for putting into effect in the Low Countries the disastrous reforms of Joseph II.

5. This and the following document were clearly written on the same day and on the same business, a favor requested by the French Ambassador. The second note speaks of the Frenchman’s being in Scotland, and his tour of the British Isles was in 1772: London Chron., Sept. 17–19, Nov. 17–19, 1772.
6. For Adrien-Louis de Bonnières, comte de Guines (1735–1805), the French Ambassador to St. James’s from 1770 to 1776, see Larousse, Dictionnaire universel, under Guines.
7. BF had clearly replied to Belgioioso’s written inquiry, perhaps by giving the bearer an oral message; in all likelihood he had offered to order the armonica.
