Cephalonomancy or cephalomancy combines the Greek root "cephalo-" (from "kephalḗ") meaning "head" or "skull" with the suffix "-mancy" which indicates divination or prophecy. 

Cephalonomancy (also known as cephaleonomancy or kephalonomancy) is an ancient form of dinvineing the name of someone guilty of a crime.  The divination process used two different methods; one was concerned with the shape of the skull, somewhat like extispicy or phrenology. The other involved heating the skull of a donkey^[1] or goat^[2] while reciting various phrases, often the names of criminal suspects.^[3] If the skull crackled or the jaw moved while a name was spoken, this was taken to identify the guilty party.

Cephalonomancy is certainly less dainty than reading tea leaves.

It is also something I didn't know existed and that there is a word for it. Just proves that there are more things in heaven and earth than I have dreamt of. So much to still learn!

@Myr, I hope whatever noises you must have been suffering while posting this have stopped.
