It appears that the Fresnal lens has been around longer than I
realized.  I should have thought that it was used in lighthouses for
many years.  I was thinking of Fresnel lenses as being only the plastic
ones we started seeing in overhead projectors in the 60's.  Thanks for
all who corrected me in e-mail and on the net.  I guess my point that
the society in BRAZIL had stagnated is made even stronger by this.
