_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._

1. If two particles of iron lie near each other without motion, and
afterwards approach each other; it is reasonable to conclude that something
besides the iron particles is the cause of their approximation; this
invisible something is termed magnetism. In the same manner, if the
particles, which compose an animal muscle, do not touch each other in the
