PLATE II

Tracing taken in the normal waking state and also under the influence of more complicated sensory stimuli. It shows the conditions of the patient under different mental states. The first part of the curve in the first tracing is perfectly normal; the second part of the first tracing shows the influence of the galvanic current; the second tracing, under the influence of different painful stimuli such as the faradic current and pricking. The third tracing shows the influence of intense sound stimuli. The rest of the tracings show the conditions of the patient in different mental states under the influence of more complicated stimulations, such, for instance, as reading to her passages from books, making her do mental calculations, singing to her, or telling her funny stories.
