] Ok, so... does Catherine now like them because now she associates them with Milsom St (the Tilney's address in Bath)? How did Eleanor teach Catherine to love them? And why is she embarrassed at Henry's inquiry?

Perhaps I'm making the question undeservedly deeper than it really is, but with his fine irony Henry is throwing about terms from the education theory that was developed right at the second half of the 18th century. Rousseau's Emile in theory and Swiss teachers in practice began putting forth the idea of "teaching through pupil's loving bond with a teacher". It was a great controversy, whether a young mind, tabula rasa, should be taught by slapping it against the reality or by logical explanation. The proving case, as far as I remember, was of a baby trying to touch a candleflame: whether to allow a small burn that will teach him/her to the end of natural life, or explain that it was "no-no" (accident or argument). It was a philosofical dispute whether the nature of aesthetic perseption lay in emotion ("sympathy to object") or in logical explanation of its features ("argument") - Gerard, An Essay on Taste.
