To break a stone in the bladder.
Take a live fox and a rabbit and cut off their heads and with care collect all their blood. Then put it in a clean pot with a cover and close it up with dough around so it cannot leak any steam and put it in the oven until everything is dried so you can make powder of it, very fine and sifted. Put in the head, all the blood, the feet and the skins and the livers of both. The flesh you can eat. Follow the method described above and care for this powder as if it were a great treasure and more to those who have need of it. If you do not believe it, observe this test. Take a spoonful of this powder and put it in a bowl or clean little pot with wine or water or broth and also vinegar and put in a stone and cover it well and keep it in a warm place for 6 to 8 days and you will find the stone broken in several pieces. In this way you will be satisfied and certain. Then for the person with a problem, take a spoonful of this powder and give a good bowlful of it in warm wine, chicken broth or with lemon water in the form of a syrup early in the morning and also you can give it some times when the patient has eaten only a little in the evening. When he takes it, he should take care of himself and keep all the body warm and in a few days, through God's grace, he will urinate the stone. When he feels the stone, have patience that soon he will be cured. You should know that this has been proved.
If by chance a man may suffer from a serious cough, he should drink this powder in the morning with wine or warm broth and also eat it on his food. He should stay warm and soon he will be cured and will not cough any more. You should know that this water has great ability to break the stone in the bladder and make it come out rapidly. If you will do this the patient will be cleared of the stone.

Another to break the stone. It is a great secret.
Take some white onions and distill them in a glass still and give 6 ounces of it warm with a little sugar. Make fine powder of those little bones that are found in groups in the feet of the hare and put in 1 dram of it. And if you have drunk it for 3 or 4 mornings and do not feel any movement, add ½ dram of powder made of climbing ivy seed and it will have a more rapid effect and shortly you will feel a stirring up in the bladder and you will urinate profusely and soon you will be cured.

Another to break the stone and in bladder and in the kidney.
Take a goat of 2 years in the month of August and at the half moon and kill it after it has eaten nothing for a month before except climbing ivy. Collect all the blood and distill it in a glass still with a slow fire and save the liquor that comes out as something valuable. In the morning early, drink 4 ounces warm with sugar in it and also bathe the pubic area, the penis and the rump and stay in repose for 2 hours but do not sleep. Do this for 6 to 8 mornings and you will see a very good effect. It will break the stone in the bladder and even in the kidney and you will urinate very copiously in a short time. If you wish to test this distillation, make it warm and put therein a stone and leave it in this stew for 6 to 8 days and you will see the result that the stone is in very minute pieces. Similarly it breaks a diamond that is put in this liquor and if one did drink a little of it he would survive but he should be careful of it.
If you take the stone that is in the head of the snail without a shell and make fine powder of it and give it early in the morning to drink with warm white wine and sugar and continue this for 8 mornings, the stone will be broken. Even if it may have been old and hard, you will urinate it soon. This has been tested.
