The September number of the 'Journal of the Polynesian Society', 1976, will contain a report by Norma McArthur (Research School of Pacific Studies, ANJ), I.W. Saunders and R.L. Tweedie (Division of Mathematics and Statistics , CSIRO) on their first series of computer simulations of very small populations. Some preliminary results of these experiments were presented at an ANU Prehistory seminar in April 1975, and a more mathematical treatment of the project was published in the first volume of CSIRO' S 'The Mathematical Scientist', 1976.
