s into action._ 5. _Induces the organ into convulsive
or fixed spasms._ 6. _Produces paralysis of the organ._ V. Of stimulus
less than natural. 1. _Stimulus less than natural occasions
accumulation of sensorial power in general._ 2. _In particular organs,
flushing of the face in a frosty morning. In fibres subject to
perpetual stimulus only. Quantity of sensorial power inversely as the
stimulus._ 3. _Induces pain. As of cold, hunger, head-ach._ 4. _Induces
more feeble and frequent contraction. As in low fevers. Which are
frequently owing to deficiency of sensorial power rather than to
deficiency of stimulus._ 5. _Inverts successive trains of motion.
Inverts ideas._ 6. _Induces paralysis and death._ VI. Cure of increased
exertion. 1. _Natural cure of exhaustion of sensorial power._ 2.
_Decrease the irritations. Venesection. Cold. Abstinence._ 3. _Prevent
the previous cold fit. Opium. Bark. Warmth. Anger. Surprise._ 4.
_Excite some other part of the system. Opium and warm bath relieve
pains both from defect and from excess of stimulus._ 5. _First increase
the stimulus above, and then decrease it beneath the natural quantity._
VII. Cure of decreased exertion. 1. _Natural cure by accumulation of
sensorial power. Ague-fits. Syncope._ 2. _Increase the stimulation, by
wine, opium, given so as not to intoxicate. Cheerful ideas._ 3. _Change
the kinds of stimulus._ 4. _Stimulate the associated organs. Blisters
of use in heart-burn, and cold extremities._ 5. _Decrease the
stimulation for a time, cold bath._ 6. _Decrease the stimulation below
natural, and then increase it above natural. Bark after emetics. Opium
after venesection. Practice of Sydenham in chlorosis._ 7. _Prevent
unnecessary expenditure of sensorial power. Decumbent posture, silence,
darkness. Pulse quickened by rising out of bed._ 8. _To the greatest
degree of quiescence apply the least stimulus. Otherwise paralysis or
inflammation of the organ ensues. Gin, wine, blisters, destroy by too
great stimulation in fevers with debility. Intoxication in the
slightest degree succeeded by debility. Golden rule for determining the
best degree of stimulus in low fevers. Another golden rule for
determining the quantity of spirit which those, who are debilitated by
drinking it, may safely omit._

I. _Of fibrous contraction._
