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.
