Who knows what unsuspected truth, what new science, indeed, may grow out of these investigations, as chemistry budded out from alchemy? “Alchemy may be compared to the man who told his sons he had left them gold buried somewhere in his vineyard; where they, by digging, found no gold, but by turning up the mould about the roots of the vines, procured a plentiful vintage. So the search and endeavors to make gold have brought many useful inventions and instructive experiments to light.”
