Crystals are worn as Jewels, or otherwise applied externally.

maintaining the economy of our daily life in active operation. Indeed,
when too violent, or too lasting, they positively injure. " This
uselessness," says a recent able journalist, " deserves our close
consideration; it seems to hold behind it some fair secret." " Our
