(_c_) The B. and R. Company requested me to pay a professional call on one of their officers. On my way to him I was engrossed in the thought that I must already have been in the building occupied by the firm. It seemed as if I used to see their signboard in a lower story while my professional visit was taking me to a higher story. I could not recall, however, which house it was nor when I had called there. Although the entire matter was indifferent and of no consequence, I nevertheless occupied myself with it, and at last learned in the usual roundabout way, by collecting the thoughts that occurred to me in this connection, that one story above the floor occupied by the firm B. and R. was the _Pension Fischer_, where I had frequently visited patients. Then I remembered the building which sheltered both the company and the _pension_. I was still puzzled, however, as to the motive that entered into play in this forgetting. I found nothing disagreeable in my memory concerning the firm itself or the _Pension Fischer_, or the patients living there. I was also aware that it could not deal with anything very painful, otherwise I hardly would have been successful in tracing the thing forgotten in a roundabout way without resorting to external aid, as happened in the preceding example. Finally it occurred to me that a little before, while starting on my way to a new patient, a gentleman whom I had difficulty in recalling greeted me in the street. Some months previously I had seen this man in an apparently serious condition and had made the diagnosis of general paresis, but later I had learned of his recovery, consequently my judgment had been incorrect. Was it not possible that we had in this case a remission, which one usually finds in _dementia paralytica_? In that contingency my diagnosis would still be justified. The influence emanating from this meeting caused me to forget the neighbourhood of the B. and R. Company, and my interest to discover the thing forgotten was transferred from this case of disputed diagnosis. But the associative connection in this loose inner relation was effected by means of a similarity of names: the man who recovered, contrary to expectation, was also an officer of a large company that recommends patients to me. And the physician with whom I had seen the supposed paretic bore the name of Fischer, the name of the _pension_ in the house which I had forgotten.
