Antipodes

"Since he was not in the grave, I could bear, I thought, to learn that he was at the Antipodes." (Bronte 428).

"Antipode" refers to an area far remote--the opposite side of the earth from one's location. At this point in the novel, Jane has just learned from a man at the inn that Mr. Rochester is not dead--but as to his current location she is unsure. Here she is saying that since she knows now that he is not dead, she could stand to hear that he was "at the Antipodes"--that is, the farthest place from here, as long as he was alive.
