ntinued,
even when the degree of fear is small; as in young men about to be examined
for a degree at the universities the frequency of making water is very
observable. When this anxiety is attended with a sleepless night, the
quantity of pale urine is amazingly great in some people, and the
micturition very frequent.

4. _Diarrhoea a timore._ The absorbent vessels of the intestines invert
their motions by direct consent with the skin; hence many liquid stools as
well as much pale urine are liable to accompany continued fear, along with
coldness of the skin. The immediate cause of this is the decreased
sensorial power of association, which intervenes between the actions of the
absorbents of the cold skin, and those of the intestinal absorbents; the
motions of the latter become on that account weakened and at length
retrograde. The remote cause is the torpor of the vessels of the skin
catenated with the pain of fear, as explained in Sect. XVI. 8. 1.

The capillaries of the skin consent more generally by direct sympathy with
those of the lower intestines, and of the bladder; but by reverse sympathy
more generally with those of the stomach and upper intestines. As appears
in fevers, where the hot skin accompanies indigestion of the stomach; and
in diarrhoeas attended with cold extremities.

The remote cause is the torpor of the skin owing to its reverse sympathy
with the painful sensual motions, or ideas, of fear; which are now actuated
with great energy, so as to deprive the second link of associated motions
of their due share of sensorial power. It is also probable, that the pain
of fear itself may contribute to exhaust the sensorial power, even when it
produces no muscular action. See Class IV. 2. 2.

5. _Pallor et tremor a timore._ A retrograde action of the capillaries of
the skin producing paleness, and a torpor of the muscular fibres of the
limbs occasioning trembling, are caused by their reverse associations with
the ideas or imaginations of fear; which are now actuated with violent
energy, and accompanied with great pain. The cause of these associations
are explained in Sect XVI. 8. 1.

These torpid actions of the capillaries and muscles of the limbs are not
caused immediately by the painful sensation of fear; as in that case they
would have been increased and not decreased actions, as occurs in anger;
where the painful volition increases the actions of the capill
