fundamental biological discovery which only now, several years later, commences to find favor among the professors.

3. A little while before, a patient gave me the medical history of her brother, who, exclaiming "Nature, Nature!" had gone out of his mind. The doctors considered that the exclamation arose from a study of Goethe's beautiful essay, and indicated that the patient had been overworking. I expressed the opinion that it seemed more plausible to me that the exclamation "Nature!" was to be taken in that sexual meaning known also to the less educated in our country. It seemed to me that this view had something in it, because the unfortunate youth afterwards mutilated his genital organs. The patient was eighteen years old when the attack occurred.

The first person in the dream-thoughts behind the ego was my friend who had been so scandalously treated. "I now attempted to clear up the chronological relation." My friend's book deals with the chronological relations of life, and, amongst other things, correlates Goethe's duration of life with a number of days in many ways important to biology. The ego is, however, represented as a general paralytic ("I am not certain what year we are actually in"). The dream exhibits my friend as behaving like a general paralytic, and thus riots in absurdity. But the dream thoughts run ironically. "Of course he is a madman, a fool, and you are the genius who understands all about it. But shouldn't it be the other way round?" This inversion obviously took place in the dream when Goethe attacked the young man, which is absurd, whilst any one, however young, can to-day easily attack the great Goethe.
