当狗的去乙酰化血液在半径约为100 μ m的玻璃管中快速流动时，离管壁5-20 μ m的边缘区的透光率变大。该区域的宽度和透射率增加的幅度在不同的血液样品中变化很大，但与伴随流速增加的表观粘度降低的幅度没有相关性。可以得出结论，在这些实验中，轴向运动的红细胞，并形成一个边缘区的红细胞浓度降低，是定量不足以占的血液的表观粘度的降低，增加流速。
When dog''s defibrinated blood was made to flow rapidly in a glass tube of about 100/x radius, the optical transmittance of a marginal zone, 5-20[mu] from the tube wall, became greater. The width of this zone and the magnitude of the increase in transmittance varied very greatly in different samples of blood, but showed no correlation with the magnitude of the reduction in apparent viscosity which accompanied the increase in rate of flow. It is concluded that in these experiments, axial movement of the red cells, and the formation of a marginal zone of reduced red cell concentration, was quantitatively inadequate to account for the reduction in the apparent viscosity of the blood with increase in the rate of flow.
