My first girlfriend's family, found s strange book under a couch cucusion after a relative visited. It was in another language, and had a funny diagram on the front, and many more inside! Well the family had, a few set backs after the relative left, and before they found the book! Well it had to be demonic with all those strange symbols all though it! They burned it and everything she had used, sheets, towels, a barrel full of stuff. Everything burned, except the book! More prof it was demonic! They soaked it in kerosene overnight, piled a bunch of wood on it, and lit it up! Burned for 2 hours, still some of it remained! They took it somewhere and buried it!
Some years later, a German chemistry teacher had a copy, it was all about chemistry! And very old, and worth a good sum of money!
The relative was a chemical major in college!
