	Sometime in college I saw a graph of the transmission functions
	of air and water both compared to the sensitivity of the human
	eye, as a function of wavelength.  The eye's response fit into a
	wide peak in air's transmission but was almost an exact match to
	water.  I thought the graph I saw was in the Feynman Lectures on
	Physics, but I can't find it there now.  Maybe somebody else has
	seen the like somewhere?
