HOLES IN SKULLS

MR. LEHR READ SOMEWHERE THAT EXPLORERS FOUND SOME SKULLS WHICH
WERE BELIEVED TO BE ABOUT 1000 YEARS OLD. THESE SKULLS WERE
FOUND IN SOUTH AMERICA. EACH SKULL HAD A PERFECTLY ROUND HOLE
IN IT.
THIS RELATES TO A PIECE IN "THE WORLD BOOK" ABOUT A TREPHINING.
THIS IS A INSTRUMENT WHICH CUTS A PERFECTLY ROUND HOLE IN A
SKULL. IT HAS EXISTED FOR THOUSANDS OF YEARS AND IS BELIEVED
TO HAVE BEEN USED TO LET OUT THE EVIL SPIRITS IN A PERSON.
