Samples. Brown coal lithotype samples were taken from a bore core from the Flynn field in the Loy Yang region of the Latrobe Valley, Victoria, Australia. The brown coal deposits in this area are believed to be Miocene to Eocene in age. All five lithotype samples were taken at depths between 93 and 100.5 m below the surface in a 120-m core and were provided by the SECV. The black coal sample was from the Upper Hunter region (Permian) of New South Wales (Sydney Basin), Australia, and had a carbon content of 81.3%, dry, ash-free basis (DAF). This sample was provided by the Australian Coal Industry Research Laboratories Ltd. (ACIRL). The characteristics of these samples are set out in Table II. 

The authors thank the State Electricity Commission of Victoria for provision of the brown coal samples and the analytical data on them, the Australian Coal Industries Research Laboratories Ltd. for provision of the black coal sample, and the National Coal Research Advisory Council for financial assistance. We also thank J. K. Emmett for helpful discussions. 

In 1967 the BKW technique was written in FORTRAN and became generally available for use on any computer that could use codes in the FORTRAN IV language. In the next decade, the code was used by the Center of Scientific and Technical Explosive Research, Sterrebeeck, Belgium the Swedish Detonic Research Foundation the Swedish Research Institute of National Defense the Australian Materials Research Laboratories and Weapon Research Establishment the Department of Reaction Chemistry of the University of Tokyo and the National Chemical Laboratory for Industry in Kanagawa, Japan. 

The author gratefully acknowledges the co-operation and help he has received from the Australian Coal Industry Laboratories (ACIRL), the Melbourne Research Laboratories of the Broken Hill Proprietary Co. Ltd. (MRL/BHP), the Commonwealth Scientific and Industrial Research Organization (CSIRO), in providing information and data, often unpublished, to assist in the preparation of this paper. In particular, he wishes to thank Dr. N. White (MRL/BHP), Mr. J. Cudmore (ACIRL), and the following former colleagues in CSIRO - Prof. A.V Bradshaw, Dr. D. Jones, Mr. H. Rottendorf,... 

Editor s Note. The symbolism used in this article is that of A. L. G. Rees of the Australian Commonwealth Scientific Research Industrial Organization, while that used by other authors in the symposium is that of F. A. Kroger and H. J. Vink of Phillips Research Laboratories. This was pointed out to the author, who feels that, of the accepted symbolisms for defect solids, that of Rees is best suited to convey the chemical and structural information required. 

The Baas Becking Laboratory is supported by the Commonwealth Scientific and Industrial Research Organization, the Bureau of Mineral Resources and the Australian Mineral Industries Research Association, Ltd. We extend our appreciation to Mrs. V.M. Barhatov for the preparation of illustrations.
