The CaCl2 concentration, M X 10~4, was constant in all experiments. There were two ways of varying the NaCl concentration: first, by replacing a part of the NaCl solution by isotonic glucose solution, thus avoiding changes in the osmotic pressure for all solutions containing less NaCl than corresponds to the isotonic concentration; second, without the cm. 35 34 33 32 31 30 29 28 27- 26. 25- 24- 23 22- 21- 20. 0 20 40 60 80 100 120 140 160 180 min.
