Library of Congress #56-13365.
Not sure if it's going to be available, but I'd reccomend it. It has an English Translation (by Louise Varese) alongside the French.
Edit: There's a
preview on Google books...can't be that impossible to find.
Edit 2: Found a
modern version on Amazon, with a Translation by John Ashbery, but it doesn't have the original French text.
I emailed the Special Collections and Rare Books division of the Library of Congress...they should be back to me in 5 business days, they say.
