PRESSAVIN, Nouveau traité des vapeurs, 1771

Second edition.
The "vapors" mental disorder popularized by Pierre Pomme, foreshadows what will be discussed under the term Hysteria in the 19th century.

"Contrary to Pomme, Pressavin does not condemn passions without restriction [...] vapors would correspond to a dysfunction of the relational system which binds living beings to the outside world; vapors can just as easily be passionate, in the grip of an overexcited sensitivity , that an indifferent, vegetating in a state of torpor. " Paul Hoffmann, "The Woman in the Thought of Lights", Slatkine, 1995
