When the Milk leaves a Cow (Spell)

From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:

When the Milk leaves a Cow.

Take a new earthen vessel, for which you must pay without bartering. In this dish place the water of such an afflicted cow, whilst calling the three highest names; also put a knife, with three cents, in the dish. Thereupon put the dish in a locked chest, and this chest again in another larger chest, and the latter in a trough, so that the earthen vessel is closed up by three locks. If, after this, somebody calls to obtain someĀ­thing from you, do not give it to him.

The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
