Ohhh, sorry --  I didn't see this e-mail message until it came through
again, embedded in another, just now on Sunday afternoon.  But lessee here,
if I remember correctly you mentioned something about a calcite crystal
that showed a rainbow inside if you oriented it correctly, and then said
something about prismatic calcite -- so I thought you were alluding to the
calcite crystal acting like a prism to disperse light into a spectrum.  I
appreciated the subltety of that joke, the "prismatic" referring not to the
crystal habit but to its optical properties.  Intended or not, that was
really good, I thought.  Keep 'em coming!

              Cheers-   Earl
