Hall effect on oscillatory hydromagnetic free convective flow of a visco-elastic conducting fluid past an infinite vertical porous plate in the presence of dissipation has been analysed. The problem is formulated with the development of constitutive equations of the flow and the solutions are obtained by applying small parameter regular perturbation technique. The velocity and temperature profiles are plotted. Numerical values of shear stresses and the rate of heat transfer are entered in the tables. It is observed that the speed of flow is minimum for Newtonian flow and increases for non-Newtonian flow. The resulting temperature is fluctuating. Similar nature is noticed in case of primary and secondary velocity. Increase in non-Newtonian parameter (RC) and external magnetic field strength(M) reduce the shear stresses
