The linear stability theory of magnetostatic equilibria in general magnetic media is developed in analogy with the corresponding theory of Bernstein, Frieman, Kruskal and Kulsrud (1), but by a different méthod which makes use of a Cauchy stress tensor analogous to that defined for a general elastic material. The self-adjointness of the stability theory is established by a new method. Application is made to fluids that are type II superconductors. Two-dimensional and axisymmetric magnetostatic equilibria are found. It is shown that the state of uniform density, entropy and magnetic field is unstable.
