Too unwell with influenza to come to London for 6 May [1823], finds it "mortifying" after having been so well over the winter. Hopes to attend Linnean Society anniversary meeting, will stay at [Thomas] Forster's in Clapton, [Middlesex], so as to prepare for the London air, and only the Society will bring him to London this spring, as he must decline visits, sights, and lecturing. Just informed that [Antoine] Gouan of Montpellier, [France], has died. Afraid Bishop of Carlisle [Samuel Goodenough] is ill, he wrote a "very melancholy" letter on death of his granddaughter.
