EXPERIMENTS PERFORMED' WITH THE SECOND METHOD In order to check these results more than 100 experiments were performed with the second method. Figure 4 illustrates the course of fatigue after the muscles have been immersed in solutions of different CaCl2 concentrations. The curves I and II show the fatigue curve of the two muscles when stimulated in the moist chamber. One recog- nizes that they behave identically. After this they were immersed. FIG. 4. Stimulation of a pair of sartorii in a moist chamber with maximal condenser discharges 90 times per minute. Then muscle I is immersed in M NaCl + M X 10~4 KC1 + M X 10"4 CaCl2 (control fluid) and muscle II in M NaCl + M X 10~4 KC1 + 81 M X 10~4 CaCl2 for nine minutes. Thereafter stimulation in a moist chamber as before (curve la, Ha respectively). The numbers at the curves indicate the time in minutes after the beginning of stimulation. for nine minutes in solutions of NaCl + KCL + CaCl2 which were alike save for the CaCl2 concentration. This was M X 10~4 in the first case and 81 M X 10~4 in the latter one. Finally they were trans-.
