摘要:

The uptake of fluid in porous material is observed in an experiment which is simple to perform and which yields results of precision better than 1%. In agreement with theory appropriate to a horizontal blotter, the square of the distance traveled by the liquid is proportional to the time. For glycerol solutions the slope of this curve is shown to be proportional to the inverse of the square root of their viscosities.
