LETTER TO THE EDITOR

The density of complex eigenvalues of random asymmetric matrices is found in the large-N limit. The matrices are of the form where A is a matrix of independent, identically distributed random variables with zero mean and variance . The limiting density is bounded. The area of the support of cannot be less than . In the case of commuting with its conjugate, is expressed in terms of the eigenvalue distribution of the non-perturbed part .
