Actually, I came to this museum because it had Loulou, the stuffed parrot from Flaubert's "Un Coeur Simple." Almost every undergraduate student of French has to suffer through this story, so I had to see her. She was a lot smaller than I imagined and resided in the closet of the room where Flaubert was born, but luckily there was much more to the museum.
It was extraordinarily interesting. The museum is devoted to the life of Flaubert, particularly his formative experiences as the son of the chief surgeon of the Hotel-Dieu. It constantly relates his writings to the various exhibits on 19th century medicine. There is a cabinet of anatomical curiosities, an exhibit on phrenology, a section on clubfoot (you remember one of the most horrible scenes of Madame Bovary?); I seem to recall a mummy. However, I think the best parts were the sections on childbirth and the dangers of childhood in the 19th century. The former section had a completely handsewn 18th century birthing dummy set to help future midwives practice delivering and recognizing problems with babies. The latter talked about abandonment, feeding problems, disease, etc., and various advancements in 19th medicine.
I seriously recommend this museum. There is not much information in English, but many of the exhibits are self-explanatory.
