ब्राह्मणस्य प्रेत कार्ये यो गौर् मार्यते तस्य अस्थि मज्ज चूर्ण पूर्णा अहि भस्त्रा पशूनाम् अन्तर् धानम् ॥
The slough of a snake filled with the powder of the bones and marrow or fat of the cow sacrificed during the funeral rites of a Bráhman, can, when put on the back of cattle, render them invisible.
