A Few More Athapaskan and Sino-Tibetan Comparisons

cross-sectioning, with mapping, might need to increase without bound in order to describe linguistic phenomena. Since I do share with Mr. Hockett and Mr. Lamb the credentials of a non-mathematician,4 I am unable to prove this necessity of an infinite number of levels (read strata) but at the moment am convinced of its validity. This, I think, is the telling argument against Mr. Lamb's model as well as an explanation of the proliferation of strata as his work has expanded. In short we should entreat Mr. Lamb to give us not merely a finite grammar but a finite model for grammar. UNIVERSITY OF CALIFORNIA, DAVIS
