What does Jim tell Huck about his daughter Elizabeth?

Jim tells Huck that he once beat his daughter for not listening to him. Sadly, it wasn't until later that he realized that she was deaf.

Oh, Huck, I bust out a-cryin’ en grab her up in my arms, en say, ‘Oh, de po’ little thing! De Lord God Amighty fogive po’ ole Jim, kaze he never gwyne to fogive hisself as long’s he live!’ Oh, she was plumb deef en dumb, Huck, plumb deef en dumb—en I’d ben a treat’n her so!
