is removed and does not return unless there be a new or similar cause.
2. In the anamnesis of many cases of anxiety neurosis we find in both men and women a striking fluctuation in the intensity of the appearances in both the coming and going of the whole condition. This year was almost wholly good, the following was terrible, etc.; on one occasion the improvement occurred after a definite treatment which, however, failed to produce a response at the next attack. If we inform ourselves about the number and the sequence of the children, and compare this marriage chronicle with the peculiar course of the neurosis, the result of the simple solution shows that the periods of improvement or well being corresponded with the pregnancies of the woman during which, naturally, the occasions for preventive relations were unnecessary. The treatment which benefited the husband, be it Father Kneip's or the hydrotherapeutic institute, was the one which he has taken after he found his wife was pregnant.
3. From the anamnesis of the patients we often find that the symptoms of the anxiety reurosis are relieved at a certain time by another neurosis, perhaps a neurasthenia which has supplanted it. It can then be regularly demonstrated that shortly before this change of the picture there occurred a corresponding change in the form of a sexual injury.
Whereas such experiences, which can be augmented at pleasure, plainly obtrude upon the physician the sexual etiology for a certain category of cases, other cases which would have otherwise remained incomprehensible can at least without gainsaying be solved and classified by the key of the sexual etiology. We refer to those numerous cases in which everything exists that has been found in the former category, such as the' appearance of anxiety neurosis on the one hand, and the specific moment of the coitus interruptus on the other, but yet something else slips in, namely, a long interval between the assumed etiology and its effect, and perhaps other etiological moments of a non-sexual nature. We have here, for example, a man who was seized with an attack of palpitation on hearing of his father's death, and who since that time suffered from an anxiety neurosis. The case cannot be understood, for up to that time this man was not nervous. The death of the father, well advanced in years, did not occur
