From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
For the Fever.
Take the water of the patient and mix it with some flour and make a dough thereof, of which seventy-seven small cakes are made, each one as large as a lintel; proceed before sunrise to an ant-hill and throw the cakes therein. As soon as the insects have devoured the cakes, the fever vanishes. Probatum.
