The literature dealing with quantitative rheography is reviewed. Particular attention is given to the reference parameters used (amplitude, basic resistance, distance between the electrodes), and the formulae proposed for flow values. The experimental evidence shows that, allowing for limitations imposed (for the most part) by the apparatus required, the pattern given by a segment of the body can be seen as that of a series of resistances in parallel, whose variations can readily be predicted. In agreement with other workers, it is felt that quantitative evaluations of blood flow can be made in this way.
