R., "The Stability of Couette Flow in an Axial Magnetic Field," Canadian J. Phys., 36, 1509-1525 (1958). These papers deal with the case of two cylinders rotated in the same direction; the case when they rotate in opposite directions has recently been investigated and will be published in due course. 2 Velikhov, E.
