Henry H writes (15.1.04):
I have an answer to one of your questions. Boringly, it's the one about Henry
Dr Sloper smells ailanthus trees in Washington Square. Dormer in The Tragic Muse smells a "queer, damp smell, partly the odour of plastic clay, of the studios of sculptors, ... somehow, identical with the general sharp contagion of Paris". Basil Ransom in The Bostonians appraises the smells outside his New York window, which include a "strong odour of smoked fish, combined with a fragrance of molasses". And in Portrait of a Lady, Isabel is talking to Ralph about the Pacific and says that "a strong, sweet, fresh odour seems to rise from it, and Henrietta - pardon my simile - has something of that odour in her garments".
So much for Seymour Chatman.
Any other examples gratefully received.
