Summary. Hydromagnetic flow and heat transfer between two horizontal parallel plates, where the lower one is a stretching sheet and the upper one is a porous solid plate are studied in the presence of a transverse magnetic field. Fluid velocities and temperature distributions are obtained and plotted graphically. The study to be reported herein, which is an extension of [5], considers the flow and heat transfer in the presence of another stationary porous plate through which there is a uniform injection. Fluid motion is due to the stretching of the plate and the injection through the upper solid porous plate. It is observed that when the injection velocity and
