Nevertheless, they do not think that Thomson, holding another Chair should give the lectures which are in the duty of a Regius Professor of Medicine. Asks him if he has any other name to suggest. Asks him also what remuneration Thomson and the future lecturer should receive. The Museum Jubilee Celebration was a success. Will send him his Address.
