Migration distance of 31 kinds of dyes in the horizontal type apparatus permitting evaporation with acetic acid solutions of 30% and 4% were measured. At the same time, adsorption analysis with the above acet_??_e acid solutions, disclosed the existance of a close relation between the extent of influence of osmotic flow into filterpaper due to the evapo-ration from the paper surface and the displace-ment ratio (R values) in adsorption analysis with the same filterpaper. In consideration with these facts migration directions of dyes were examined in the above solution.
