    The author points out that some of the published materials on invariant polynomials of several matrix arguments are incorrect. It is remarked that the mistake mainly arose as a result of substituting non-symmetric arguments in the formulas for invariant polynomials. Specific details of the mistakes are examined and the correct procedure to be followed is pointed out in this paper.
