     “We can however say that, with electrolytes, the effects are always lyotropic. Sulphates, tartrates, etc., raise the point of solidification, decrease the period of solidification, and increase the rate of change of the viscosity with the time. They therefore help the solidification.”

   • 1910, The British Journal of Photography, volume 57, p. 631:

     It is interesting to note that sulphates head of of Freundlich’s lyotropic series; but I fear that this is merely a coincidence.
