   The articles referred to, concerning the use of 30 angstrom cutoffs in
 simulations of lipid bilayer systems, are as follows:
 1) H. E. Alper, D. Bassolino, and T. R. Stouch, J. Chem. Phys. 98 (12),
    9798 (1993)
 2) H. E. Alper, D. Bassolino, and T. R. Stouch, J. Chem. Phys. 99 (7),
    5547 (1993)
    Anyone interested in reprints of these, or other articles dealing with
 diffusion of solutes through lipid bilayers, can send me their address
 information.
