Possible Observation of a Second Kind of Light - Magnetic Photon Rays
  Several years ago, I suggested a quantum field theory which has many attractive features. (1) It can explain the quantization of electric charge. (2) It describes symmetrized Maxwell equations. (3) It is manifestly covariant. (4) It describes local four-potentials. (5) It avoids the unphysical Dirac string. My model predicts a second kind of light, which I named ``magnetic photon rays.'' Here I will discuss possible observations of this radiation by August Kundt in 1885, Alipasha Vaziri in February 2002, and Roderic Lakes in June 2002.
