since the introduction of cocaine; I would not betray by a single sign that I had had a share in making this discovery. With this phantasy were connected thoughts of how difficult it really is for a doctor to claim the medical services of a colleague for his own person. I should be able to pay the Berlin eye specialist, who did not know me, like anyone else. Only after recalling this day-dream do I realise that the recollection of a definite experience is concealed behind it. Shortly after Koller's discovery my father had, in fact, become ill with glaucoma; he was operated upon by my friend, the eye specialist, Dr. Koenigstein. Dr. Koller attended to the cocaine anæsthetisation, and thereupon made the remark that all three of the persons who had shared in the introduction of cocaine had been brought together on one case.
I now proceed to think of the time when I was last reminded of this affair about the cocaine. This was a few days before, when I received a Festschrift, with whose publication grateful scholars had commemorated the anniversary of their teacher and laboratory director. Among the honours ascribed to persons connected with the laboratory, I found a notice to the effect that the discovery of the anæsthetic properties of cocaine had been made there by K. Koller. Now I suddenly become aware that the dream is connected with an experience of the previous evening. I had just accompanied Dr. Koenigstein to his home, and had spoken to him about a matter which strongly arouses my interest whenever it is mentioned. While I was talking with him in the vestibule, Professor Gärtner and his young wife came up. I could not refrain from congratulating them both upon their healthy appearance. Now Professor Gärtner is one of the authors of the Festschrift of which I have just spoken, and may well have recalled it to me. Likewise Mrs. L., whose birthday disappointment I have referred to, had been mentioned, in another connection, to be sure, in the conversation with Dr. Koenigstein.
I shall now try to explain the other determinations of the dream content. A dried specimen of the plant accompanies the monograph as though it were a herbarium. A recollection of the gymnasium (school) is connected with the herbarium. The director of our gymnasium once called the scholars of the
