ADDITIONAL I N F O R M A T I O N FOR "PETFAB" Griffis, R. A., Gustafson, S. J., and Adams, H. G., 1985, Computers Geosciences, v. 11, no. 4, p. 369--408. I would like to suggest that a particularly appropriate reference is missing from the paper by Griffis, R.A., Gustafson, S.J. and Adams, H.G., 1 9 8 5 (PETFAB: User-considerate FORTRAN 77 program for the generation and statistical evaluation of fabric diagrams, Computers & Geosciences v. I I, no. 4, p. 369--408); namely a reference to the paper by Starkey, J.,

1970, A computer programme to prepare orientation diagrams, in Experimental and natural rock deformation, edited by Paulitsch, P. Springer-Verlag, Berlin, p. 51-74.
