Stokes writes: 'In a letter to me, dated March 29, 1854, the late Dr W Bird Herapath enclosed for me some iridescent crystals of chlorate of potash, which he thought were worth my examination. He noticed the intense brilliancy of the colour of the reflected light, the change of tint with the angle of incidence, and the apparent absence of polarisation in the colour seen by reflection. The crystals were thin and fragile, and rather small.'
