A model is developed for a triple catch marking experiment on two areas with migration between the two areas and death or emigration occurring. Estimates of the parameters of the model are derived. Some of these estimates are shown to be suitable even under certain restrictions on migration (e.g. animals may be restricted to a single transfer in the course of the experiment). Variances of the estimates were not derived but some rules were developed, based on computer simulations, to guide the experimenter in planning experiments and in judging the precision of his estimates.
