Suleiman and Munson (1981) recently presented a sequence of experiments concerning the buckling of thin viscous fluid layers. In their paper the authors referred to Taylor's (1968) observations on the buckling of slender viscous filaments. His early observations and the Suleiman and Munson experiments point toward an important analogy between the buckling of elastic columns and the buckling of viscous filaments in longitudinal compression. The object of the comment is two-fold. First, it brings to the readers' attention the fact that a buckling theory of thin viscous layers already exists. Second, it points out that the buckling of slender columns in axial compression is not a property only of elastic solids and highly viscous fluids, but also a property of inviscid columns (streams). Munson replies stating that the theory developed by Buckmaster et al. (1975) for the buckling of a viscida does not, apply to the buckling of a thin viscous layer described by Suleiman and Munson (1981)
