CaCl, (lower curve). Effect of Varying KCl and Together Since an excess of KCl in Ringer's solution increases the rate and an excess of CaCl., decreases it, when both salts are present in excess we should expect to find typical antagonism. This may be tested ex- TABLE VII Percentage of change in rate for 5 minutes on addition of KCl (1) to 100 vols. NaCl and (2) to 100 vols. NaCl plus 15 vols. CaCl,,.
