“The old-timers,” Merle as well feeling his way, “used to believe that if you took away from mercury everything not essential, the liquid-metal business, the shine, the greasy feel, the weight, all the things that make it ‘mercury,’ see, you’d be left with this unearthly pure form of it the cupel ain’t been made that can hold it, somethin that would make this stuff here seem dull as traprock. Philosophic Mercury, ’s what they called it, which you won’t find anyplace among the metals of metallurgy, the elements of the periodic table, the catalogues of industry, though many say it’s really more of a figure of speech, like the famous Philosopher’s Stone—supposed to really mean God, or the Secret of Happiness, or Union with the All, so forth. Chinese talk. But in fact these things, they’ve been out there all along, real material things, just not easy to get to, though alchemists keep tryin, it’s what we do.”
