Especially noteworthy were the pair at 495.9 and 500.7 nm (known as N1 and N2

At around the same time spectral lines in gaseous nebulae were attributed to a
further element called nebulium. It was of course not obviously true that all of the
lines in either case were produced by one element or that coronium and
