Forwarded Smith's letter to Mrs Smith. Firmly against allowing [Richard] Salisbury to "desecrate the name Castalia" and make it serve for the denomination of a plant inhabiting "foul, stagnating, fetid water" [Castalia was a nymph transformed into a fountain by Apollo]. Additionally objects to it on grounds of being contrary to the rules of analogy and its being a Greek word, thus having nothing to do with Latin etymology. Discusses in detail Dioscorides' nomenclature in reference to Smith's proposed 'Blephara' genus and suggets either 'Nuphar' or 'Madonia'. Suggests correction to Smith's 'Blephara' character. Still receiving invitations to dinner from the Geological Society after repeatedly stating that he cannot join them or any other dining society.
