Safely returned home, his departure necessitated by his being "feverish weak" and unable to attend to anything; treating himself with James's powder but "felt so sudden a relief even at Mile End, [...] as if some great mental as well as bodily evil were suddenly taken off". Urges Macleay to change his situation as recommended, as though many have "a frame of adamant, a soul of fire" [Samuel Johnson (1709-1784), writer] and can bear the airs of London, "many sink under them"; recounts how he himself "struggled for 7 years in [Great] Marlbro' Street".

Received Macleay's packet but only just able to respond; much pleased with the address. "What an alarming thing is this murder!". Nursing himself in order to be able to travel to London in stages to finish his lectures and attend Linnean Society anniversary meeting, which he has never yet missed.

Too ill to attend Linnean Society anniversary meeting, the first time he has missed "that happy & flattering day". He is now trying bark for his fever, and hopes to be in London for 2 June to finish his lectures, "a great object" to him. His "dear friend & relation", Mrs Kindersley, has just died, leaving 8 children. Will ask the Bishop of Carlisle [Samuel Goodenough] to preside at Society meeting.

Still ill, and can "hardly go up or down stairs without exhaustion", though the bark has stopped his intermittent fever many times. He and the Bishop of Carlisle [Samuel Goodenough] agree on electing the Bishop of Durham [Brownlow North] an Honorary Member, will appoint the vice-presidents by letter, as he did with [Thomas] Marsham.
