Note 2 — Chapter X · THE PSYCHES: THE CASES
Alexander Teixeira de Mattos translation

Would they behave likewise towards animal materials and especially mineral materials, on condition that these are of a suitable thinness? I take a Great Peacock’s wing, left over from my experiments in the nuptial telegraphy of this Moth,2 and cut from it a strip on which I place, at the bottom of a tube, two little caterpillars stripped of their clothing. The two prisoners have nothing else at their disposal. Any drapery that they want must be got out of this scaly expanse.
