whose most remarkable findings in anesthetics we have had no experience.
Hence, to the often cited axiom, "Hypnosis is artificial hysteria," we would like to add another: "The existence of hypnoid states is the basis and determination of hysteria." These hypnoid states in all their diversities agree among themselves and with hypnosis in the fact that their emerged presentations are very intensive but are excluded from the associative relations of the rest of the content of consciousness. The hypnoid states are associable among themselves, and their ideation may thus attain various high degrees of psychic organization. In other respects the nature of these states and the degree of their exclusiveness differ from the rest of the conscious processes as do the various states in hypnosis, which range from light somnolence to somnambulism, and from perfect memory to absolute amnesia.
If such hypnoid states already exist before the manifested disease they prepare the soil upon which the affect establishes the pathogenic memories and their somatic resulting manifestations. This behavior corresponds to the predisposed hysteria. But the results of our observations show that a severe trauma (like that of a traumatic neurosis) or a painful suppression (perhaps of a sexual affect) may bring about a splitting of presentation groups even in persons otherwise not predisposed. This would then be the mechanism of the psychically acquired hysteria. Between the extremes of these two forms we have to admit a series in which the facility of dissociation in the concerned individuals and the magnitude of the affect of the trauma vary inversely.
We are unable to give anything new concerning the formation of the predisposed hypnoid states. We presume that they often develop from "reveries" very common to the normal for which, for example, the feminine handwork offers so much opportunity. The questions why "the pathological associations" formed in such states are so firm and why they exert a stronger influence on the somatic processes than other presentations, all fall together with the problem of the effectivity of hypnotic suggestions in general. Our experiences in this matter do not show us anything new, on the other hand they throw light on the contradiction between the sentence "Hysteria is a psychosis" and the fact that among hysterics one may meet persons of the clearest
