But against high chymic tests no sham can stand; and first it is too light in weight, and second, when rubbed on this Basanus or Black-stone, traces no line of white, as any diamond must. But, third and last, I have tried it with the hermeneutic proof, and dipped it in this most costly lembic; and the liquor remains pure green and clear, not turbid orange, a diamond leaves it.
