Volume 2 contains Mildmay's private accounts of conferences and negotiations held with the French commissioners from 1750 to 1754.

Volume 3 contains letters from Mildmay to Benjamin Mildmay, the Earl Fitzwalter, during his time in Paris. The letters serve as an ongoing description of Mildmay's time in France, and they document issues surrounding the negotiations, politics, foreign relations, social events, and the activities of the French court. Included is an account of the governmental crisis that arose from a dispute between the French Parliament and clergy. Mildmay also recorded details related to his personal life and social events, including a description of a party with dramatic fireworks at the Duke of Orleans's palace, in honor of the Dauphin's recovery from smallpox (September 27, 1752). The letters reveal that Mildmay was growing increasingly frustrated by the treaty negotiations; in a letter from January 24, 1753, Mildmay wrote, "I am now in full business with the French Commissaries, & heartily sick of their chicanery; but it is to be hoped His Majesty will put an end to all wrangling & disputes by a happier method of accommodation, or more persuasive arguments than what are delivered in written Memorials." In addition, he mentioned that if they are to enter into a war with France, it would be against the will of the people in the country, but if they are to maintain peace, France would only use it to prepare for a later war (March 26, 1755). Mildmay discussed specific issues with the negotiations, such as the British refusing to agree to an article that stated if France and Britain went to war, neither would commission privateers to disrupt commerce (March 6, 1754). Due to the physical condition of this volume, it is currently unavailable for use except via microfilm. Please contact the library for more information.
