Dear Conch-list colleagues,

A few years ago, I heard of a shell book that illustrated x-rays of shells.
I had tried to purchase a copy, but it was out of print.  I now have another
source for out-of-print books, but can't recall the title or author of the
book.  I seem to recall it had a title that may have included the word
"Dimensions," but that hasn't facilitated my search.

Is anyone familiar with such a publication?  Thank you for your help in
trying to track down this book.
