In the case of the cataleptic, during the entire duration ofthe observation, the lever which corresponds to the extendedmember traces a straight and perfectly regular line (fig. 2, II). During the same time, in the case of the simulator, thetracings at first resemble those of the cataleptic, but, at the 6 J. M. CHARCOT AND P. RICHER. end of a few minutes, very considerable differences begin tomake their appearance : the straight line changes into aline sharply broken and characterized by instants of largeoscillations arranged in series (fig. 3, II)..

The tracings furnished by the pneumograph are equallysignificant. In the case of the cataleptic, the respirationsare infrequent and superficial, the end of the tracingresembling the beginning (fig. 2, I). In the case of the simu-lator, the tracings are composed of two distinct portions. CEREBRAL AUTOMATISM. 7 In the beginning the respiration is regular and normal. Inthe second phase, that which corresponds to the indicationsof muscular fatigue noticed in the tracings of the extendedmember, there may be observed irregularity in the rhythmand amplitude of the respiratory movements, deep andrapid depressions, indicative of the disturbance of respira-tion that accompanies the phenomena of effort (fig. 3, I). ?I ? ^^~^f,-^^4^ mw^wxm Fig. 3.—Diagrammatic representation of the tracings ob
