The bowl contains one or two elements which will only mix with the others at a certain temperature, and as an experiment it is successful because I have kept the unmixable elements in suspension, though the liquid has gone cold."
"The Man Who Knew"
Edgar Wallace
I respected him right enough in his place, as I trust he respected me in mine, but though fate thought fit for the present to place us in the one groove, yet our lives were unmixable commodities as oil and water, which lay apart and would never meet until taken in hand by the omnipotent leveller-death.
"My Brilliant Career"
Miles Franklin
