The initial manner of development of an infinitesimal disturbance of a plane horizontal layer of a viscous, perfectly conducting, incompressible fluid of variable density in the presence of a horizontal magnetic field is discussed. It is found that when the coefficient of viscosity muo be such that d2 nu o/dz2 < 0, instability might arise in the form of oscillation with increasing amplitude i.e., overstability. This shows that contrary to the usual role of viscosity as a damping factor, it may sometimes act as a destabilizing agent. Furthermore, it is seen that a sufficiently strong magnetic field may stabilize a potentially unstable configuration.
