Family Discovers A 160-Year-old Skull In An English Pub With A Hidden Note Inside It

So, What Was It?

The family was sitting quietly in the living room while Dr. Wagner was going through other details of the skull. He seemed pretty much lost in the skull. The family called out his name but there was no response from his side as he was that much into the skull. The family waited for Dr. Wagner to tell them something or anything about the skull but they had to wait a little longer as all he said to the family was that he needed to take this skull back to the lab.
