To cause a Cow to give plenty of Milk (Spell)

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

To cause a Cow to give plenty of Milk.

When a cow bears the first calf, give her half of an eel's tail in half a loaf of bread, or however best it may be given, and the cow will certainly give a great deal, of milk.

The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
