1829: Thomas Moore, Memoirs, Friday the 16ᵗʰ of January entry 16 [Friday] — Walked over to Bowood dinner — Lord L. showed me after dinner a letter he had received from Lord Anglesey, explaining the circumstances that led to his recall & to the publication of his letter to Curtis — very well written, & both the style & the feeling showing him to have been fully capable of the letter to the Archbishop — one word in it rather an odd coinage — “upholdatory of his government” — set off at nine for the Ball — the Houltons there, looking very handsome — Kerry, all happiness & I tant soi peu ennuyé — Got to Bowood between 2 & 3 — my intention was to return home, but Lady L. persuaded me to stay & sleep.
