Regarding terminology: In the 70s a man by the name of Chenall (I think that's how you spell it) created a book of museum nominclature--it was not exhaustive (although that was the goal) however, it was very good. I became familiar with it when I worked at the Whatcom Museum in Washington State. If you like, call Jan Olsen, curator of collection at the Whatcom (360) 676-6981. John Handley
