I don't care much whether I ever get to know anything - but I want to work out something in figures - something that hasn't got to do with human beings. I don't want people particularly. In some ways, Henry, I'm a humbug - I mean, I'm not what you all take me for. I'm not domestic, or very practical or sensible, really.And if I could calculate things, and use a telescope, and have to work out figures, and know to a fraction where I was wrong, I should be perfectly happy, and I believe I should give William all he wants.
