Query: Charge to Magnetic Flux Ratios   It is shown that if the carriers in the fractional quantum Hall effect are
taken as geometrical excitations with quanta of charge e and magnetic flux
h/2e, as proposed in a previous publication, the calculated results are
compatible with the series of fractions obtained experimentally.
