You could have a look to this thread where I transcribed the original french text of one of Etteilla's book:
"Manière de se récréer avec le jeu de cartes nommés Tarots - Troisième Cahier"
and where AT member MikeH made a complete english translation!

And in this thread:

MikeH added the "Supplément au troisième cahier" that I do not own.
BTW I would like to take the opportunity to add that MikeH attempt to translate Etteilla's very heavy and obscure style was a great effort and a great contribution for english speaking people who are interested in early original text about Tarot.
