While in a particularly happy mood he let the number 426,718 come to his mind, and put to himself the question, “Well, what does it bring to your mind?” First came a joke he had heard: “If your catarrh of the nose is treated by a doctor it lasts 42 days, if it is not treated it lasts—6 weeks.” This corresponds to the first digit of the number (42 = 6 × 7). During the obstruction that followed this first solution I called his attention to the fact that the number of six digits selected by him contains all the first numbers except 3 and 5. He at once found the continuation of this solution:—

“We were altogether 7 children, I was the youngest. Number 3 in the order of the children corresponds to my sister A., and 5 to my brother L.; both of them were my enemies. As a child I used to pray to the Lord every night that He should take out of my life these two tormenting spirits. It seems to me that I have fulfilled for myself this wish: ‘3’ and ‘5,’ the evil brother and the hated sister, are omitted.”

“If the number stands for your sisters and brothers, what significance is there to 18 at the end? You were altogether only 7.”

“I often thought if my father had lived longer I should not have been the youngest child. If one more would have come, we should have been 8, and there would have been a younger child, toward whom I could have played the rôle of the older one.”

With this the number was explained, but we still wished to find the connection between the first part of the interpretation and the part following it. This came very readily from the condition required for the last digits—if the father had lived longer. 42 = 6 × 7 signifies the ridicule directed against the doctors who could not help the father, and in this way expresses the wish for the continued existence of the father. The whole number really corresponds to the fulfilment of his two wishes in reference to his family circle—namely, that both the evil brother and sister should die and that another little child should follow him. Or, briefly expressed: If only these two had died in place of my father![71]

Another analysis of numbers I take from Jones.[72] A gentleman of his acquaintance let the number 986 come to his mind, and defied him to connect it to anything of special interest in his mind. “Six years ago, on the hottest day he could remember, he had seen a joke in an evening newspaper, which stated that the thermometer had stood at 98·6° F., evidently an exaggeration of 98·6° F. We were at the time seated in front of a very hot fire, from which he had just drawn back, and he remarked, probably quite correctly, that the heat had aroused his dormant memory. However, I was curious to know why this memory had persisted with such vividness as to be so readily brought out, for with most people it surely would have been forgotten beyond recall, unless it had become associated with some other mental experience of more significance.

“He told me that on reading the joke he had laughed uproariously, and that on many subsequent occasions he had recalled it with great relish. As the joke was obviously of an exceedingly tenuous nature, this strengthened my expectation that more lay behind. His next thought was the general reflection that the conception of heat had always greatly impressed him, that heat was the most important thing in the universe, the source of all life, and so on. This remarkable attitude of a quite prosaic young man certainly needed some explanation, so I asked him to continue his free associations. The next thought was of a factory stack which he could see from his bedroom window. He often stood of an evening watching the flame and smoke issuing out of it, and reflecting on this deplorable waste of energy. Heat, flame, the source of life, the waste of vital energy issuing from an upright, hollow tube—it was not hard to divine from such associations that the ideas of heat and fire were unconsciously linked in his mind with the idea of love, as is so frequent in symbolic thinking, and that there was a strong masturbation complex present, a conclusion that he presently confirmed.”

Those who wish to get a good impression of the way the material of numbers becomes elaborated in the unconscious thinking, I refer to two papers by Jung[73] and Jones.[74]

In personal analysis of this kind two things were especially striking. First, the absolute somnambulistic certainty with which I attacked the unknown objective point, merging into a mathematical train of thought, which later suddenly extended to the looked-for number, and the rapidity with which the entire subsequent work was performed. Secondly, the fact that the numbers were always at the disposal of my unconscious mind, when as a matter of fact I am a poor mathematician and find it very difficult to consciously recall years, house numbers, and the like. Moreover, in these unconscious mental operations with figures I found a tendency to superstition, the origin of which had long remained unknown to me.

It will not surprise us to find that not only numbers but also mental occurrences of different kinds of words regularly prove on analytic investigation to be well determined.
