‎First appearance of the paper in which Pasteur announced his finding that the only legitimate exception to his law (law of optical activity and crystalline form) was one which he himself had discovered"" amyl alcohol which shared with a few other compounds the property of being optically active in the absence of crystalline asymmetry but which also displayed in its mode of crystallization unique features that convinced Pasteur that any ""hidden"" asymmetry could never be revealed.‎
