From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
Take the entrails of a trout caught between Christmas and New Year, and put them upon a copper lid. Burn them to powder. Put it into the stock of your gun. Also in a little bag, and hang it under the right arm. You will then be able to shoot whatever you desire. If you carry the same under your left arm, you will be gay and happy.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
