Dora asked me to-day how it was I knew all about these things, whether Hella had told me. I did not want to give Hella away, so I said quite casually: Oh, one can read all about that in the encyclopedia. But Dora laughed and said: You are quite on the wrong scent; you can’t find a tenth of all those things in the encyclopedia, and what you do find is no good. In these matters it is absolutely no good depending on books. First of all she would not tell me any more, but after a time she told me a good deal, especially the names of certain parts, and about fertilisation, and about the microscopic baby which really comes from the husband, and not as Hella and I had thought, from the wife. And how one knows whether a woman is fruitful.
