Membranes (history)
Pomme
"membranous tissues like pieces of damp parchment...peel away with some slight discomfort, and these were passed daily with urine; the right ureter also peeled away and came out whole in the same way", and in description of the intestines reads: "peeled off their internal tunics, which we saw emerge from the rectum. The oesophagus, the arterial trachea, and the tongue also peeled in due course; and the patient had rejected different pieces either by vomiting or by expectoration." Cited by Michel Foucault in The Birth of The Clinic (p. ix)
