Fold together, and tie it in grayish red cloth, which must be unbleached, and pierce through the cloth and the letter, three holes. Draw red thread through them, while calling the three holiest names. Suspend the same around the neck of the patient, and let it remain eleven days. After taking it off, burn it before the lapse of one hour:H B R H C H T H B R H
