punishment.

19. _Citta._ A desire to swallow indigestible substances. I once saw a
young lady, about ten years of age, who filled her stomach with the earth
out of a flower-pot, and vomited it up with small stones, bits of wood, and
wings of infects amongst it. She had the bombycinous complexion, and looked
like a chlorotic patient, though so young; this generally proceeds from an
acid in the stomach.

M. M. A vomit. Magnesia alba. Armenian bole. Rhubarb. Bark. Steel. A
blister. See Class I. 2. 4. 5.

20. _Cacositia._ Aversion to food. This may arise, without disease of the
stomach, from connecting nauseous ideas to our usual food, as by calling a
ham a hog's a----. This madness is much inculcated by the stoic philosophy.
See Antoninus' Meditations. See two cases of patients who refused to take
nourishment, Class III. 1. 2. 1.

Aversions to peculiar kinds of food are thus formed early in life by
association of some maniacal hallucination with them. I remember a child,
who on tasting the gristle of sturgeon, asked what gristle was? And being
told it was like the division of a man's nose, received an ideal
hallucination; and for twenty years afterwards could not be persuaded to
taste sturgeon.

The great fear or aversion, which some people experience at the sight of
spiders, toads, crickets, and the like, have generally had a similar
origin.

M. M. Associate agreeable ideas with those which disgust; as call a spider
ingenious, a frog clean and innocent; and repress all expressions of
disgust by the countenance, as such expressions contribute to preserve, or
even to increase, the energy of the ideas associated with them; as
mentioned above in Species 17. Ira.

21. _Syphilis imaginaria._ The fear that they are infested with the
venereal disease, when they have only deserved it, is a very common
insanity amongst modest young men; and is not to be cured without applying
artfully to the mind; a little mercury must be given, and hopes of a cure
added weekly and gradually by interview or correspondence for six or eight
weeks. Many of these patients have been repeatedly salivated without curing
the mind!

22. _Psora imaginaria._ I have twice seen an imaginary itch, and twice an
imaginary diabaetes, where there was not the least vestige of either of
those diseases, and once an imaginary deafness, where the patient heard
perfectly well. In all these cases the hallucinated idea is so powerfully
excited, that it is not to
