The history of man on this planet from prehistoric times until now is a continuous whole. There is no fact, however remote, that does not have a bearing of greater or less importance on the destiny of the whole human race. Much has been buried, lost, forgotten but within manís consciousness is a burning desire to know as much of as possible. Within the past four centuries this desire has increased until today there is no civilized land without a museum. In these museums are mementos of the past which though they might seem valueless to some, are precious to those scientist, scholar, thinker.
