Two recent theoretical approaches that of Charnes, Raike, and Bettinger 1972 and that of A. G. Wilson 1967 to the gravity model of spatial interaction are examined with emphasis on the dissimilar physical and statistical theories from which they were respectively deprived. Formal relationships between the two methods are demonstrated. The two approaches jointly indicate a general method of generating new hypotheses of gravity flows. This method is discussed and evaluated, and some questions of theory comparability are explored. Comments on some of the computational features of each of the two models conclude the paper. Author
