The level and the trends of the per acre yield of wheat in England from the middle ages down to date were ingeniously demonstrated by M. K. Bennett in his article contributed to the Economic History in 1935. But the progress of the study of English economic history since then has rendered some of his conclusions untenable. The writer intends to make necessary modifications of Bennett's curve, the result of which is seen on the chart prited on p. 23.

Linear and nonlinear viscoelastic properties of disperse systems of photosensitive particles were studied in relation to the degree of aggregation of dispersing particles. The disperse system has the characteristic long-time relaxation process attributed to the aggregate structure of dispersing particles. In that relaxation process, the system in which the dispersing particles aggregate in some degree shows markedly nonlinear viscoelasticity. The characteristic relaxation time in the long-time relaxation process can be closely related with the rotational diffusion of the aggregate. It is also shown that the characteristic relaxation time is independent of the dynamic strain amplitude.
