Herculine Barbin

Hi!
Would anyone happen to know of any works published which deal
specifically with Foucault's discovery of the Herculine Barbin fonds in the
archives of the French Department of Public Hygiene? Is there any other
information available on her case that was not included in Foucault's book?
As Foucault commented on the case in any of his other works? Any assistance
would be greatly appreciated.
