To Walk Upon a Hot Iron Bar.
Take half an ounce of camphor, dissolve it in two ounces of aqua vitæ, add to it one of quicksilver, one ounce of liquid storax, which is the droppings of myrrh, and prevents the camphor from firing; take also two ounces of hematis, which is a red stone, to be had at the druggists’; and when you buy it, let them beat it into a powder in their great mortar, for, being very hard, it cannot well be reduced in a small one; add this to the ingredients already specified, and when you purpose to walk upon the bar, anoint your feet well with it, and you may do so without the slightest danger.
