Allthought of a change of form of the foldsof the mucous membrane, on account of amovement of their own, has been com-pletely ignored. But a closer study of thestructure of the relief of the folds of themucous membrane of the intestines onanatomical preparations and on the livingintestines will give rise to another view. areas a and d of the lower preparation, it will be noted that in spite of the duo-denum having the same outer width, areaa has low, simple folds, few in number, anda wide lumen, whereas area d has high, complicated, closely-placed folds and inarrow lumen.
