e is on the passing current of his ideas, the greater surprise he
experiences on their being dissevered by some external violence, as
explained in Sect. XIX. on reverie.

As in these constitutions more than the natural quantities of sensitive
motions are produced by the increased quantity of sensation existing in the
habit, it follows, that the irritative motions will be performed in some
degree with less energy, owing to the great expenditure of sensorial power
on the sensitive ones. Hence those of this temperament do not attend to
slight stimulations, as explained in Sect. XIX. But when a stimulus is so
great as to excite sensation, it produces greater sensitive actions of the
system than in others; such as delirium or inflammation. Hence they are
liable to be absent in company; sit or lie long in one posture; and in
winter have the skin of their legs burnt into various colours by the fire.
Hence also they are fearful of pain; covet music and sleep; and delight in
poetry and romance.

As the motions in consequence of sensation are more than natural, it also
happens from the greater expenditure of sensorial power on them, that the
voluntary motions are less easily exerted. Hence the subjects of this
temperament are indolent in respect to all voluntary exertions, whether of
mind or body.

A race of people of this description seems to have been found by the
Spaniards in the islands of America, where they first landed, ten of whom
are said not to have consumed more food than one Spaniard, nor to have been
capable of more than one tenth of the exertion of a Spaniard. Robertson's
History.--In a state similar to this the greatest part of the animal world
pass their lives, between sleep or inactive reverie, except when they are
excited by the call of hunger.

III. _The Temperament of increased Voluntarity._

Those of this constitution differ from both the last mentioned in this,
that the pain, which gradually subsides in the first, and is productive of
inflammation or delirium in the second, is in this succeeded by the
exertion of the muscles or ideas, which are most frequently connected with
volition; and they are thence subject to locked jaw, convulsions, epilepsy,
and mania, as explained in Sect. XXXIV. Those of this temperament attend to
the slightest irritations or sensations, and immediately exert themselves
to obtain or avoid the objects of them; they can at the same time bear cold
and hunger better than others, of
