This year is the 50th anniversary of one of the most spectacular of all archaeological discoveries, the almost untouched tomb of an ancient Egyptian pharaoh. After four years' intensive work, the treasure was removed to the National Museum in Cairo but the mummy of the pharaoh was resealed in its coffin in the tomb. Recently, the coffin was reopened so that a scientific X-ray study of the mummy could be made by a team led by Professor R. G. Harrison, of the Department of Human Anatomy, Liverpool University.
