1. "a log of the enquiry itself"
2. "a notebook for gathering information in such way that it is possible to simultaneously to keep all the items in a chronological order and dispatch them into categories."
3. "a notebook for ad libitum writings trials"
4. "a notebook to register the effects of the written account on the actors whose world has been either deployed or unified."
