"After a while the host invited us into a separate area where the magnetic bathhouse was. I should say that animal magnetism is the favourite drawing room entertainment here, it has totally overtaken ancient card-games, dice, dancing and other games. This is how it’s done: one person stands at the bath, usually it’s someone with more experience of magnetic manipulation. All the others take in their hands a lead which is attached to the bath and then the magnetization begins. This puts some people into a kind of magnetic sleep, which is good for the health; others it seems to have no effect on at all. But some people go into a trance, and that’s the fun of it. As I was completely unaccustomed to it, the magnetism had no effect on me. But this meant that I was able to observe everything that happened."
