"No, indeed I can't," replied Stephen. "It is a complete mystery to me. My uncle Jeffrey was a confirmed old bachelor, and, although he did not dislike women, he was far from partial to their society, wrapped up as he was in his favorite studies.

I could not tell what her age was, or what she was like, because her head was wrapped up in a sort of knitted, woolen veil to keep out the fog.
