A DISPLAY case with a controlled environment, developed by the Getty Conservation Institute in California, made it possible to put Egypt's royal mummies back on public view this month. After being perfectly preserved underground for three millenniums or more, excavated mummies are threatened by light, temperature and humidity changes and are liable to decay. The case has a nitrogen atmosphere that will prevent dangerous bacteria and other microbes from causing decay.
