He supported the mortmain bill in April 1736. He was on the common council of the Georgia Society till 1739, when he resigned, professedly on the ground that his private business would not allow him to attend board meetings, but actually because, like his first cousin, George Heathcote, he considered the board too subservient to Walpole.2HMC Egmont Diary, ii. 452; iii. 22, 83, 92; Harley Diary.
