The signs thus far discussed are not found spread about in an arbitrary way through the whole experiment, but are seen in very definite places, namely, where the stimulus words strike against emotionally accentuated complexes. This observation is the foundation of the so-called "diagnosis of facts" (_Tatbestandsdiagnostik_). This method is employed to discover, by means of an association experiment, which is the culprit among a number of persons suspected of a crime. That this is possible I will demonstrate by the brief recital of a concrete case. On the 6th of February, 1908, our supervisor reported to me that a nurse complained to her of having been robbed during the forenoon of the previous day. The facts were as follows: The nurse kept her money, amounting to 70 francs, in a pocket-book which she had placed in her cupboard where she also kept her clothes. The cupboard contained two compartments, of which one belonged to the nurse who was robbed, and the other to the head nurse. These two nurses and a third one, who was an intimate friend of the head nurse, slept in the room where the cupboard was. This room was in a section which was occupied in common by six nurses who had at all times free access to the room. Given such a state of affairs it is not to be wondered that the supervisor shrugged her shoulders when I asked her whom she most suspected. Further investigation showed that on the day of the theft, the above-mentioned friend of the head nurse was slightly indisposed and remained the whole morning in the room in bed. Hence, unless she herself was the thief, the theft could have taken place only in the afternoon. Of four other nurses upon whom suspicion could possibly fall, there was one who attended regularly to the cleaning of the room in question, while the remaining three had nothing to do in it, nor was it shown that any of them had spent any time there on the previous day. It was therefore natural that the last three nurses should be regarded for the time being as less implicated, so I began by subjecting the first three to the experiment. From the information I had obtained of the case, I knew that the cupboard was locked but that the key was kept near by in a very conspicuous place, that on opening the cupboard the first thing which would strike the eye was a fur boa, and, moreover, that the pocket-book was between some linen in an inconspicuous place. The pocket-book was of dark reddish leather, and contained the following objects: a 50-franc banknote, a 20-franc piece, some centimes, a small silver watch-chain, a stencil used in the lunatic asylum to mark the kitchen utensils, and a small receipt from Dosenbach's shoeshop in Zürich.
