administered or used by any rational physician.14 That powdered hematite (red oxide of iron) possesses an astrin­gent quality and may really be looked upon as a medicine, he fully recognizes, more particularly its efficacy for the cure of diseases of the eye, but neither these nor similar qualities can be credited to sapphires, emeralds, or jacinths. At the same time he is not disposed to deny that these stones may have some subtle effect upon the body when worn, or when held in the mouth for a time. Thus he agrees with Avicenna (Ben Sina) that a jacinth worn over the heart may strengthen that organ, for he knows of the power inherent in jasper to check a hemorrhage.
