The long axis of the house, has a direction 20° W. of north. The room occupied by the Sotto Intendente with his family on the 16th December, is a nearly square one, on the first floor (i.e., one over the ground floor). They had not gone to rest, and he was first alarmed by a short, sharp rattling, with a jumping vertical movement of about half an inch, of a large white metal chocolatière, that stood upon a marble-topped table at a, touching both the south and west walls.
