        *Webster's School Dictionary, 1980:::::::*

                "Ozone n 1: a form O3 of Oxygen that has three atoms
                in the molecule, is a faintly blue irritating gas
                with a pungent odor . . ."

        Maybe your high-school chemistry teacher was like mine - the gym
instructor!  But then he did say that if you wanted to smell ozone, ride
a trolleycar thru the tunnel!
