est possible limit consistent with life, and to such a degree as
to simulate actual death. At other times considerable mental excitement
will accompany the cataleptic symptoms, and the patient will sing or
utter passionate exclamations during the fit, being all the while quite
unconscious. The attack may be of short duration, passing off within a
few minutes. It may, however, last for many hours, and in some rare
instances persist for several days; and it is conceivable that in such
cases the appearances presented might be mistaken for real death, as is
alleged to have occasionally happened. Catalepsy belongs to the class of
functional nervous disorders (see MUSCLE AND NERVE: _Pathology_) in
which morbid physical and psychical conditions are mixed up. Although it
is said to occur in persons in perfect health, careful inquiry will
usually reveal some departure from the normal state, as is shown by the
greater number of the recorded cases. More particularly is this true of
females, in whom some form of menstrual derangement is generally found
to have preceded the cataleptic affection. Catalepsy is sometimes
associated with epilepsy and with grave forms of mental disease. In
ordinary cases, however, the mental phenomena bear close resemblance to
those witnessed in hysteria. In many of the subjects of catalepsy there
appears to be a remarkable weakness of the will, whereby the tendency to
lapse into the cataleptic state is not resisted but rather in some
measure encouraged, and attacks may thus be induced by the most trivial
circumstances.

CATALOGUE (a Fr. adaptation of the Gr. [Greek: katalogos], a register,
from [Greek: katalegein], to enrol or pick out), a list or enumeration,
generally in alphabetical order, of persons, things, &c., and
particularly of the contents of a museum or library. A _catalogue
raisonnee_ is such a list classified according to subjects or on some
other basis, with short explanations and notes. (See also articles
