I picked up Darwin's coral reef book at a second hand bookstore last
year, but have yet to read it.
I did score a nifty little shell book for ten bucks; "Wonders of the
Sea SHELLS" 15 plates in color by Paul A. Robert, IRIS BOOKS, Oxford
University Press printed in Switzerland in 1945. not much to the text,
but oh, the illustrations! They are prints from watercolors and
gorgeous. I can't make up my mind; do I keep the book intact or gut it
and frame the illustrations.
