## Abstract Monovalent cation salts induce reversal in the direction of the stroke of the cilia; bivalent and trivalent cation salts with a few exceptions do not. Some acids induce reversal, others do not. The duration of reversed action varies with the kind of salt and with the concentration. As
Factors that may influence experimental measurements of osmotic pressure are analysed. Measurements with new membranes in the osmometer show that a period of 5(~60 hr is necessary for the membrane relaxation. The influence of the porosity of the membrane upon the values of M, and A 2 for polydispers
