When the current is broken the catgut cools andrelaxes slowly. Records may be obtained in this way which arealtogether similar or identical with those given by a strip of plainmuscle when stimulated (see Figs. 28 and 29). The model may beused to show the effect of temperature upon the extent and dura-tion of the contractions, the effect of variations in strength ofstimulus as expressed in the amount of current used, the sum-mation of successive stimuli, etc. Under all of these conditionsit imitates closely the behavior of plain muscular tissue. Another somewhat similar explanation of the mechanics of contractionhas been suggested by McDougall* and has obtained support from severalobservers. According to this view the cha
