MORBID STATES OF SENSATION. 
into pain. Their healthy state borders far more upon quiescence 
than upon excitement. 
Fidget tiness . — There are certain states of the constitution in 
which there is a slight and yet unpleasant degree of exaltation of 
the sensitive nervous system — a kind of fidgettiness, than which 
there are few things more annoying. We see it in the stabled 
horse unexercised and over fed. He is not still an instant ; he 
is pawing, weaving, cribbiting, nibbling, and biting himself in 
every part. If he is taken out of the stable, he knows not what 
to do with himself ; and his rider scarcely knows what to do 
with him. He is most annoyingly and unmanageably fidgetty. 
He is worse, if possible, than the young student who cannot 
keep himself still for a moment, but worries his neighbours, and 
distracts the lecturer to a degree of which he has little con- 
ception. 
There is a species of dog, the favourite of the ladies, the de- 
testation of every man, and the essence of whose character and 
constitution is fidgettiness or perpetual motion ; — I mean the 
small French poodle. From the earliest to the latest hour he is 
in incessant action ; distinguished by no peculiar intelligence, by 
no disinterested affection, by no peculiar submissiveness even to 
those by whom he is fed. He is an apt illustration of that undue 
accumulation of irritative nervous power which torments him- 
self and all around him except his mistress; until it has found 
an outlet through which it may be expended. 
Irritability at the commencement of Disease . — There is another 
species of sensorial irritation which is more decidedly connected 
with disease; not merely a shifting of the posture, or the irre- 
gular movement of a particular limb, but a continual restlessness 
and wandering. The horse at the commencement of almost 
every febrile attack is shifting his posture and his place every 
instant; lying down and getting up again, pacing around his 
box, and measuring it in every direction. The sheep under the 
influence of the hydatid will wander to the farther part of the 
pasture; lie down, gaze mournfully around him, and then get 
up and wander again ; some strange convulsive motion of one 
of the limbs interrupting or giving a singular character to his 
walk. The dog, when rabies is about to establish itself, is the 
most irritable restless being that can be conceived of, starting 
convulsively at the slightest sound, disposing his bed in every 
direction, seeking out cne retreat after another in order to rest his 
wearied aching limbs, but quiet only for a moment in any one, 
and the motion of his lrmbs frequently simulating chorea, 
and even epilepsy. 
Pain from old Wounds and Fractures . — There is another morbid
