Case 5. H—— (20 years). On the _memory_ of the feeling of _ennui_ experienced on the first day in barracks.—"In order to _represent_ to myself thoroughly this feeling of _ennui_, which was very intense, and lasted a whole afternoon, I shut my eyes and abstract my thoughts. I feel, first, a slight shiver down my back, a certain _malaise_, a feeling of something unpleasant which I should prefer not to feel over again. After this first moment comes a certain uncomfortable state, a slight oppression of the throat; this feeling is connected with vague representations which do not fix themselves. In the experiment here described, I first picture to myself the barrack-yard, where I used to walk; then this picture of the yard is replaced by that of the dormitory on the third floor. I see myself seated at a window, looking at the view, of which I can see all the details. This, however, does not last; the picture soon disappears; there remains only a vague idea of being seated at a window, and then a feeling of oppression, weariness, dejection, and a certain heaviness in the shoulders. At this point I break off the experiment and open my eyes, still experiencing a general sense of uneasiness, which soon passes off." The whole experiment lasts a little more than ten minutes. To sum up, we have, first, a feeling of weight and oppression, a shudder in the back, but no clear representation of surrounding objects; then a feeling of discomfort becoming more and more intense, visual representations varying either in their nature or their intensity; and finally, the total disappearance of these visual representations, the feeling of _ennui_ being persistent throughout.
