The solid line represents the amount of urea in milligrams penetrating the skins in the Dextrose-Ringer's mixtures. The broken line represents the amount of urea in milligrams penetrating the skins in the control experiments when Ringer's solution alone was used. The dotted line represents the percentage of permeability on the basis of the permeability with Ringer's solution alone, which is taken to be 100 per Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
