Catalepsy
2 of the 7 encyclopedias on this shelf carry an entry for Catalepsy. Both are reproduced below, so you can see where they agree and where they differ.
An Encyclopaedia of Occultism (1920)
A condition involving the sudden suspension of sensation and volition, and the partial suspension of the vital functions. The body assumes a rigid and statuesque appearance, sometimes mistaken for death, and the patient remains unconscious throughout the attack. On occasion, the cataleptic state may be marked by symptoms of intense mental excitement, and by apparently volitional speech and action. Sometimes the symptoms are hardly distinguishable from those of hysteria. The period covered by the attack may vary from a few minutes to several days, though the latter only in exceptional cases; it may, however, recur on trifling provocation in the absence of resistence from the will-power of the patient. The affection is caused by a pathological condition of the nervous system, generally produced by severe or prolonged mental emotion, and it must not be confused with the hypnotic trance. The belief that it may occur in a perfectly healthy person is, on the whole, fallacious. There is some reason to suppose that catalepsy, like ecstacy and mediumistic faculties, may at times prove contagious. Dr. Pététin, in his Electricité Animale (1808) makes mention of as many as eight cases met with in a restricted area, although catalepsy is in ordinary circumstances of rare occurrence. Pététin also mentions certain strange phenomena witnessed by him in connection with the state of spontaneous catalepsy (see Stomach, Seeing with), which would seem to show that persons in this condition are amenable to suggestion in a high degree. The true physical reasons for catalepsy are still practically unknown to science. But there seem to be good reasons for believing that it can be self-induced in certain cases. Many Eastern fakirs have been known to cast themselves into a cataleptic sleep lasting for months and cases have even been known where they permitted themselves to be buried, being exhumed when the grass had grown over their graves. (See Dendy, Philosophy of Mystery.)
Collier's New Encyclopedia (1921)
a form of mental disorder, akin to hysteria, which is characterized by the person affected falling down suddenly in a state of real or apparent unconsciousness, and, save for some occasional muscular twi twitchings of the face and body, remaining rigid and statue-like for a period of time which varies from one minute to some hours or even days, and then all at once recovering consciousness as if aroused from sleep as a rule with no bad consequences to follow. Catalepsy almost invariably affects hysterical people only, and it is the prolongation of the unconscious condition to some days in certain extreme cases which has given rise to the fear which some people have of being buried alive under such circumstances. CATALONIA (ancient Hispania Tarraconensis), an old province of Spain, bounded N. by France, E. and S. E. by the Mediterranean, S. by Valencia, and W. by Aragon. The country in general is mountainous, but intersected with fertile valleys, while the mountains themselves are covered with valuable woods and fruit-trees, the slopes being cut in terraces and pl plentifully supplied with water by an artificial system of irrigation. Wheat, wine, oil, flax, hemp, vegetables, and almost overy kind of fruit are abundant. There are mines of lead, iron, alum, etc. On the coast is a coralfishery. Catalonia, though less fertile than most of Spain, stands pre-eminent for the industry of its inhabitants, who speak the Catalan dialect. Pop. about 2,150,000; area, 12,480 square miles. It comprises the modern provinces of Tarragona, Gerona, Lerida, and Barcelona.
