I realise that this quote is from quite while back in the novel, but I have seen the word "condescended" or "condescension" appear several times in the novel.

Here is an example from Chapter 14:

"Mr. Collins was eloquent in her praise. The subject elevated him to more than usual solemnity of manner, and with a most important aspect he protested that "he had never in his life witnessed such behaviour in a person of rank -- such affability and condescension, as he had himself experienced from Lady Catherine."
